The in flight staff was very friendly

Our 2nd flight was changed by the airline, causing us to have a 6 hour layover in Philadelphia instead of a 2 hour layover. Then when we ask about changing to a different flight they told us that the original flight we were supposed to be on (that we booked over 8 months ago) was completely full so that’s why we were moved, and there were no other flights available to switch to. So we accepted that. But when we printed our boarding passes, we saw that our seats were now separate from each other, and they were both middle seats! I don’t understand how booking my tickets so far in advance still resulted in these issues. We were finally able to get an aisle and window seat (not near each other) but both flights had poor to little entertainment, which I wouldn’t have expected on such long flights with American Airlines. Really was letdown. :(

the flight attendants and service were amazing and perfect. The green tea from All Nippon Airline was awesome.

All the food were terribly salty, inedible because the beef was hard like rock, I was unable to eat or chew. The sauce was salty and terrible so threw them away. In general, the food were inedible and poorly prepared that means they were not considerate and discreet about cooking, selecting material,too. The airline only pick the terribly cheap meat to scam and mistreat the passengers. I felt I was ripped off and sadden.

Smoothest long flight I’ve ever had. No hassles checking in, boarding or leaving the aircraft. Bags checked through to final destination without any problem. Good employees at the check-in counter and at the boarding gate. Service was good at LAX.

Cabin service somewhat spotty. I was not served breakfast and had to ask for a meal even though all those sitting around me were served. My wife did not get the coffee she requested even though it was promised twice. Trash accumulated at our seat making use of the tray awkward. I tried to pre-pay for extra luggage on-line before the flight but the web site would not allow me to do so. We paid $100 per extra bag at check-in.

I paid €60 extra to sit in the emergency door seat to get more leg room but once.i was in the plane learned for more leg room I accepted a smaller seat next to a bathroom and no entertainment. I could not store my belongings near me. No power outlet to charge my devices for my own entertainment on a 7 hour flight. Dealing with constant traffic for the bathroom. I sat in the middle seat between two hours other men. It was a constant struggle arm space. After 7hours in the air I could not wait to get off the plane. If I didn't actually pay an extra €60 for the seat I may not feel bad but I feel like I might have been better off without paying for the "upgrade"

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,
please send us an and someone from our team will get back to you promptly.
