What Counts as a Missed Connecting Flight
A missed connection happens when a flight delay, cancellation, or operational problem causes you to miss your next flight on a multi-leg journey. The reason behind the missed connection matters. If the airline caused the disruption (for example, mechanical issues or staffing problems), they’re responsible for rebooking or refunding you.
What to Do When You Miss a Connection
If you miss your connecting flight in the U.S., follow these steps right away:
- Ask for the reason in writing or request confirmation by text or email.
- Keep your boarding passes, e-tickets, and rebooking confirmations.
- Gather evidence of the disruption (photos of departure boards, screenshots from the airline app, or gate-change alerts).
- Save all receipts for meals, ground transport, and hotels if the airline did not provide them.
- Note your arrival time at your final destination (the DOT defines arrival as when the aircraft door opens).
- Communicate in writing whenever possible because this creates a clear record for refunds or reimbursement claims.
Missed Connections and Your DOT Rights
The U.S. doesn’t have an equivalent to Europe’s EU261 or UK261 regulations. Instead, passenger protections fall under DOT regulations as well as each airline’s Contract of Carriage and Customer Service Plan.
Generally, if your missed connection was caused by the airline’s delay, cancellation, or mismanagement, you are entitled to one of the following:
- A free rebooking on the next available flight (with the same class of service).
- Rerouting at a later date if the rebooking they offer doesn’t work for you.
- A refund for the unused portion of your ticket
If your flights were on separate reservations, or you missed your connection because you didn’t allow enough time between flights, the airline isn’t legally required to help, though some may still offer a goodwill option.
Can You Request Rerouting on Another Airline?
Airlines are encouraged, but not legally obligated, to find you a booking with another carrier if you have to wait hours for the next available flight. However, if you rebook an earlier alternative with another airline yourself, and the original airline refuses assistance, you can later file for reimbursement by providing documentation of the costs and your communication with the airline.
The Minimum Connection Time (MCT) & Why It Matters for Missed Flights
Every airport has an official Minimum Connection Time (MCT), which is the shortest amount of time considered reasonable to transfer between flights under normal operating conditions. This is not just a recommendation. Airlines and airports use MCT standards to build valid itineraries in their booking systems.
Flights Booked on a Single Ticket
If your connecting flights were booked together on one ticket, your airline has already confirmed that the scheduled layover meets the MCT for that airport. This means that the airline accepts responsibility for getting you to your final destination if a delay on the first leg causes you to miss your onward flight. In these situations, you won’t need to pay for a new ticket because the carrier must rebook you at no additional charge or offer a refund for the unused segment if they cannot accommodate you in a reasonable time.
Self Transfers
If you created your own connection using separate tickets, often called a self-transfer, you take on that risk yourself. Under U.S. Department of Transportation (DOT) rules, airlines are not required to protect self-made connections. So, if your first flight runs late and you miss the second one, the airline operating the next flight can treat it as a no-show and cancel your onward bookings. Then, you’ll likely have to buy a new ticket to continue your trip.
To protect yourself, always check the airport’s MCT before booking. You can find this information on airline websites or through the airport’s own transfer guidelines. MCTs vary depending on factors such as:
- Whether your connection is domestic to domestic or domestic to international
- If you need to clear security or customs between terminals
- Whether you must collect and recheck your bags
- The size and layout of the airport (e.g., changing terminals at Chicago O’Hare takes more time than connecting within one concourse at Dallas–Fort Worth)
PRO TIP: For self-booked connections, allow at least 90 minutes for domestic transfers and 2–3 hours for international ones. It’s better to have extra time than risk losing your ticket or paying hundreds for a new one.
Missed Connections on a Codeshare Flight
For codeshare flights (where one airline sells the ticket but another operates the flight), the DOT states that the operating carrier, the airline actually flying the delayed leg, is responsible for assistance or refunds.
Always direct your claim or request to the airline who was immediately responsible for the disruption that caused you to miss your connecting flight.
Meals, Hotels, and Assistance While You Wait
Under U.S. rules, airlines must clearly disclose what they offer during extended delays or missed connections. The DOT’s Airline Customer Service Dashboard (transportation.gov) shows each airline’s policy on:
- Meals or meal vouchers
- Overnight hotel stays
- Ground transportation to hotels
Not all airlines provide these benefits automatically, and when they do it will depend on whether the delay was within their control.
If You’re Denied Boarding After Rebooking
If your rebooked flight is oversold and you’re denied boarding, you’re covered under DOT oversales rules (14 CFR Part 250). This means that you may be entitled to cash compensation of up to 400% of your one-way fare (up to $1,550 in 2025) depending on the length of the delay. Always ask staff to confirm in writing that you were involuntarily denied boarding.

Missed Connections on International Flights to the UK or Europe
If you miss a connection on an international flight to or from the UK or EU, you have more rights under EU Regulation 261/2004 (EU261) or UK261.
Here’s how it works for U.S. passengers:
- If your flight departs from an EU or UK airport, you’re covered under EU261 or UK261, even if you’re a U.S. citizen.
- If your flight departs from the U.S. to the EU/UK on a European or UK-based airline (like British Airways, Lufthansa, or Air France), those same laws apply.
- Compensation under these rules can reach €600 (about $650) for long delays caused by the airline.
- If you’re forced to wait at the airport because of a missed connection, the airline must provide meals, refreshments, and access to communication once you have been delayed at least 2 hours.
How to Get a Refund or Reimbursement
If the airline’s delay or cancellation caused you to miss your connecting flight and you no longer wish to continue your trip, you have the right under U.S. Department of Transportation (DOT) rules to request a full refund instead of rebooking.
This applies even if you bought a non-refundable ticket — when the airline fails to operate the flight you purchased, you’re entitled to your money back. Refunds must cover the entire unused portion of your ticket, and if you’re stranded mid-journey, that can include the return leg as well.
If the delay was within the airline’s control (for example, due to maintenance, staffing shortages, or a schedule mismanagement issue), you may also qualify for reimbursement of reasonable out-of-pocket expenses. That includes:
- Meals purchased during the delay,
- Hotel stays if you were forced to spend the night, and
- Ground transportation to and from the airport or hotel.
To make the process smoother:
- Request written confirmation of the delay or cancellation cause because it’s key to proving the airline was responsible.
- Keep every receipt and note the exact times your flights were delayed or canceled.
- Submit your request in writing to the airline’s customer-relations department. Attach receipts, boarding passes, and copies of any messages you received from the airline.
- Follow up within two weeks if you haven’t received acknowledgement.
You don’t need to quote legal codes. Simply mention that you’re requesting a refund and reimbursement under U.S. DOT rules for controllable delays or cancellations. Clear, polite, and documented communication tends to yield better results.
How Long It Takes to Receive a Refund
Under DOT regulations, most U.S. airlines must process refunds:
- Within seven business days for credit or debit card purchases, or
- Within twenty days for payments made by cash or check.
Refunds should appear back in your account or on your card statement shortly after that period. If the airline delays or refuses, it’s often because they’re disputing whether the disruption was within their control. In these cases, continue to respond in writing and keep a record of all correspondence.
If the issue still isn’t resolved, you can file a formal complaint with the U.S. Department of Transportation’s Aviation Consumer Protection Division at airconsumer.dot.gov. DOT complaints carry weight, and airlines must respond directly to both you and the Department, which usually speeds things up.
But why waste your time and effort?
At AirAdvisor, our legal team can act on your behalf, so you get the maximum payout without the stress. Plus, it’s risk free. You don’t pay a fee unless we win your case. We can gather the evidence and negotiate directly with the airline, all without upfront costs. This means that a frustrating travel experience can be turned into a fair financial outcome.
Turning missed connecting flights into fair financial outcomes
Here are a few real examples of how AirAdvisor has helped travelers in the U.S. recover what they’re owed after missing a connecting flight.
Case 1: American Airlines – Missed Connection After Dallas Delay
In early 2025, a couple flying from Los Angeles (LAX) to Orlando (MCO) via Dallas–Fort Worth (DFW) missed their connection after a three-hour delay caused by an aircraft maintenance check. Although American Airlines rebooked them for the following morning, no hotel or meal assistance was offered.
What Happened Next
AirAdvisor reviewed the case and confirmed through flight records that the disruption was fully within the airline’s control. Under DOT guidance, passengers are entitled to a refund or reimbursement for reasonable expenses when controllable issues lead to missed connections.
The Outcome
The travelers were reimbursed $186 for hotel costs, $42 for meals, and received a $297 refund for the unused leg of their journey. AirAdvisor’s claim specialists handled the paperwork and communication directly with the airline, ensuring a fair and fast resolution.
Case 2: Delta Air Lines – Crew Scheduling Issue in Atlanta
A frequent business traveler missed a connecting flight in Atlanta (ATL) en route from Houston (IAH) to New York (JFK) after Delta delayed the departure due to a last-minute crew reassignment. The next available flight wasn’t until the following morning.
What Happened Next
The airline initially cited “operational constraints” and denied reimbursement for hotel expenses. AirAdvisor helped the passenger file a DOT-compliant claim, presenting flight documentation proving the delay was crew-related which is counted as a controllable factor under U.S. airline policy.
The Outcome
Within weeks, Delta reimbursed the passenger $172 for hotel costs, $31 for meals, and issued a $250 travel credit as goodwill. The passenger praised AirAdvisor for turning “a stressful overnight delay into a fair outcome with minimal effort.”
Case 3: United Airlines – Missed Connection at Chicago O’Hare
A family traveling from Denver (DEN) to Boston (BOS) via Chicago O’Hare (ORD) missed their evening connection after a two-hour delay caused by an inbound aircraft change. The airline rebooked them for a flight the next morning but provided no overnight assistance.
What Happened Next
AirAdvisor guided the family through the refund and reimbursement process under DOT rules for controllable delays. They submitted receipts for a nearby hotel and meals and received a written acknowledgment from United that the delay stemmed from an equipment rotation issue.
The Outcome
Within three weeks, the family recovered $412 in reimbursements and a partial refund for the unused leg. The case demonstrated how persistence, documentation, and expert help can ensure passengers aren’t left covering airline mistakes.
These examples show that even when airlines blame “operational issues” or “tight schedules,” passengers still have strong legal protections.
