Airline reviews

Flight delayed and then cancelled (due to mechanical issues + weather). Poor communication. No one there to help with rebooking and accommodations for the night we had to stay in Newark. Our luggage was taken off the original flight and apparently left on the tarmac in the rain. Items were soaking rain. The following day, the flight was also delayed due to mechanical issues. The second year in a row that I had to sleep in an airport flying from Tokyo to Newark due to mechanical issues compounded by bad weather. Partly bad luck and partly just poor service.

Terrible service - they don’t want to be there and bad food. Entertainment system in economy from the 2000s

I did bought anything… I don’t understand how this book appears to me . Ridiculous

Leaving at 7 when scheduled to leave at 4:20 - you tell me. Understood there was a ground stop. Then having to "reboot" the plane because of a lighting strike, also understood. But basically the flight was a "clusterf#$%".

No drink service but there was no N/A as an option to choose. Seats were extremely tight. I am under 5.5 and I bumped my knees have no idea how taller people could manage.

I bought this ticket for my daughter. She had to pay for her carry on bag to be checked. My understanding is that transatlantic flights included carry on and personal item The nickeling and diming fo legacy carriers has stooped to an all time low. So sad.

Both my flight where delayed Had 25min to make it to my transfer flight

I just got back from a trip with 3 flights each way. The flights were good and we were happy with out experience. There was one steward on our first flight that was harsh and grump with passengers. It did not leave a good impression. All of the other flight crews were great on the other five flights.

They changed my flight 5 hours before it took off and changed my connecting airport messing up my entire 1st day in Japan.

The Economy Plus rows weren’t as roomy as expected, and the meal service left a lot to be desired for.
