Decent boarding group, same snacks, same flight attendants (who were very nice)

My only gripe is that paying for an assigned seat is only allowed 48 hours before takeoff and costs at least $30, twice what Spirit charges to allow you to select a seat during booking, so it is worse. No one watched us to ensure that we didn’t use the overhead bins (a stipulation of the fare) but we did comply anyway. We chose to take our chances and were assigned seats at the gate 16 rows apart and both in the middle seat.

NOTHING !! I lost my flight because in the email I received you all put the wrong airline on it and nobody took responsability for it . I ended up paying $311.00 to get the next flight back to Austin .

In the email it was stated that my first flight was with British Airways, so i wasted time making the wrong line . Only to get to the counter and waste more tome trying to find me in the system to then tell me my flight is with American Airline . I double check my email where it clearly shows: 1st flight-British Airway and 2nd flight-American Airline . This is not acceptable, nobody wants to take responsability for sending me the wrong information in the email. Had I know both of my flights were with American Airline I wouldn’t lost my plane because I would make the right line to begin with .

The flight was so short we did not even get a snack, only an offer of a bottle of water; this was simply due to to short length of the flight. Basic economy had my wife and I 16 rows apart each in a middle seat. I was in the very last seat on the plane. Flight attendants were attentive and surprisingly very nice, legroom is non-existent (same as every flight in plain coach).

High cost to prebook seats was twice what Spirit or Frontier would charge

The flight got delayed from salt lake and we had to spend a day in Charlotte before another flight came

Not so good meals. For a 9 long-haul flight only one meal provided, other was a cheap candy bar. Other carriers do offer breakfast. Traveled with child and did not allow priority boarding at LHR. Limited leg room, I assume this already a trend well known by travelers.

No voo MEX-GRU o Sistema de Entretenimento nao funcionou por quase 3hs. A refeicao foi muito fraca, tamto no jantar quanto no café da manhã. Onde ja se viu comer feijão preto com onelete no cafe da manhã??? Deveriam pensar no tipo de passageiro q estao atendendo.

Our original flight was delayed and Marika, at the Delta gate of another flight to the same city, was able to get us on the flight that was going to our city. We were so grateful to get home before the winter storm! We appreciate your staff and the help their quick, efficient manner to get us on a new flight!

Very rapid flight. Landed far before scheduled arrival(at least 25 minutes). Checked baggage was delivered before schedule arrival time. Crew was pleasant/helpful.

Flight was changed from what was originally scheduled and purchased. I was informed of the change after the purchase before traveling. Thus I had 4 1/2 hours between flights.

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,
