Nice flight crew.

Frustrating. After 11 hours of travel under by belt for the day, I prepare for the final leg by removing my very small cross-body from my "personal item" so that I can easily access my passport and boarding pass. The gate crew makes me stand there and put everything away before getting on the plane while I continue to struggle with my carry-on. this could have easily been done once I was settled and buckled into my seat instead of holding up the line. I have priority boarding, clearly there is plenty of time to reorganize once I am on the plane and out of the way!

That I got a soda

Delayed at Ohare by an hour. Sitting on the Tarmac for a half hour in Reagan, waiting for a gate. This was our leg back to DC, after our leg to Chicago four days previously. On that trip I did a review and gave the whole trip a 1 out of 5 stars. That trip was the trip from hell, with delays, waiting on the Tarmac, deplaning, almost cancelled, more waiting on the Tarmac, wheels up in Reagan, wheels down in ORD, and then more Tarmac waiting for a gate. So I was already more than perturbed when this trip had similar outcomes.

Once I made it, they worked to get me on the plane from Chicago quickly.

I barely made it for my flight in Chicago and that was with running. They were already boarding the other plane when my plane from Hattiesburg landed. Earlier in the day I had to get them to change my flight from Chicago in Hattiesburg because it wasn't changed for me when the delay had my original flight leaving before I was to land in Chicago. I don't fault them for someone getting sick at the last minute or my inconvenience, but it was still inconvenient.

Seats were really neither notably comfortable nor notably uncomfortable. I think they were slightly on the comfortable side.

Would be nice to have more modern aircraft amenities, like power outlets for device charging, and display screens with at least some complimentary entertainment, or at least flight path tracking. Boarding counter lady was obnoxiously strict about not letting our carry-on bags to be carry-on. She made us test them in the size device and said they were too big, even though they could easy be pushed into the space, and regardless of the fact that we just flew on an American Airlines flight with them as carry-on and were only on a layover with them! Regarding the previous AA agent who let them be carry-on, she said "shame on them." Complete opposite of the positive experience we had with her counterpart in Phoenix. ಠ_ಠ

When we landed in Washington DC we sat on the Tarmac for an hour because there was no gate for the plane to park at. This caused me to miss my connection flight to Albany. I was put on a standby list for a flight that was leaving 7 hours later. They never offered to give me a meal voucher.

Nothing - the flight from Chicago to Philadelphia was delayed by about 2 hours. Luckily, was able to get the flight switched to a Chicago - London direct flight.

The connecting flight from Philadelphia to Manchester would've been missed. So, American Airlines booked the same flight for 24 hours later. Luckily, they offered a different flight. Due to the flight changes, the prepaid ground transportation from Manchester to Leeds wasn't used. Transportation from London to Leeds had to be purchased at a much greater additional expense.

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

We were unfortunately stuck on the tarmac for 45 minutes. I ran to my connecting gate but they had already closed it. There wasn’t a service rep at the gate. I walked to another gate and there was a very helpful rep who rebooked me to a nearby city. It overall was disappointing and caused me to get home about 3 1/2 hours later.

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 .

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.
