Good clean aircraft. Fairly comfortable seats. Even had a power outlet in my row. Not too bad for an aircraft from the late 70s.

for some reason, i had to pay to gate check a bag. It didnt seem like anyone else did while boarding my flight.

Even though I was disappointed by not being able to get the boarding passes from Delta for Aeromexico’s connecting flight to Bogota, I had an agent greet me after customs in Mexico to issue the boarding pass so I could use the transfer flight line. Excellent service throughout the entire trip.

Confusion over my boarding pass at the Delta terminal in Detroit.

Nice seats, comfortable.

Again, no aisle seat for SkyTeam Gold member. Also, my baggage was lost. First bag arrived a day late, second after I had left Billund and it was six days before the bag with my clothes reached me. I was told I will have 100 euro credit for clothing, but in the winter and for 6 days, this was not even close to the amount I needed for clothing and necessities, to have my time here.

The flight was very pleasant, with great service. The in-flight entertainment selection was good, food was tasty. The day we flew, this flight was maybe half-full in coach, which may not be great for BA, but fantastic for leg room! The attendants were lovely, and I particularly enjoyed the continuous water service through the flight, which kept me nicely hydrated. The ice-cream mid-way through movietime was a welcome treat!

Prices are per person and are for e–tickets and include all taxes & fees in USD.

We attempt to get accurate prices, however, prices are not guaranteed.

Here's why:

We’re not the seller.
At KAYAK we don’t set the prices, so it’s not possible for us to guarantee what other companies are selling.

We compile tonnes of data for you
Our service lets you quickly and easily compare results from hundreds of travel sites at once. In this sense, KAYAK is a search engine and we can't guarantee prices we find.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car rentals can change frequently. Several people may also be trying to buy the same travel option simultaneously. As a result, you may find, on occasion, that certain prices are no longer available.

If you have more questions or if you have a bad price to report to us,
