Even small, regional carriers like Danish Air Transport (DAT) can have their fair share of complaints. They operate an average of only 20-30 flights per day, but passengers may still need to contact the airline to raise a complaint or simply speak with an agent.

In this article, you’ll find the contact details for DAT as well as some helpful tips on how to lodge a formal complaint.

Before Contacting DAT by Phone

Since phone lines tend to be busy for most airlines, it’s good to know a few things before you actually call so that you can make the conversation as efficient as possible. 

1. Organize your flight information. DAT customer service agents will ask for basic information to access your booking. To save time, make sure you have all relevant details handy.
2. Prepare to wait. During busier travel seasons or if there are many flights disrupted, customer service lines can be busy for a very long time, so be patient!
3. Calls aren’t usually free. Calls to DAT may incur fees depending on your mobile carrier.

Social Media Channels for DAT

If you’re having difficulty reaching DAT by phone, you can always try writing a direct message to the airline on their Facebook page. Contacting them this way can be fast and effective, especially if you’re dealing with a canceled flight situation and need immediate help with a rebooking. 

Be careful if you choose to reach out to DAT on social media as more and more scams are targeting unsuspecting passengers!

DAT Complaints

No matter which airline you’re flying, it’s always smart to understand your basic passenger rights before you contact customer service. As a DAT passenger, you’re protected by EU261 regulations. These protect you when you have flight disruptions and can lead to as much as 600 EUR when the right conditions are met.

DAT Email Addresses

You don’t have to send a complaint in writing, but if you experience flight disruptions or baggage issues, you will have to lodge a more formal complaint, and send it to one of the email addresses below.

DAT Mailing Addresses

When you have to send hard copies of documents or other kinds of mail, you can send parcels to the following addresses.

Tips for a Favourable Outcome

1. Be thorough, but brief. Include as many details as you need to, but explain the problem clearly and directly.
2. Add all pertinent flight information. The easier it is to locate your record, the faster the airline’s response will be. So, make sure you include flight numbers, where you were travelling to and from, and your name as it was in your booking.
3. Attach supporting documents. Things like booking receipts, photos, notes from a conversation with an airline agent, and expense receipts will all help to support your claim.
4.  Be polite and persistent. Always be professional and polite in your email correspondence. If you don’t get a reply after a week or so, you can send another message to follow-up.
