The flight was on time, seats were comfortable, crew is friendly and professional. Nice flight overall. Thanks!

Both flights were on time and without in-flight issues. Although we had to check our carry-on bags at the last minute (cabins were full, no more room), our bags were on the baggage carousel very quickly. (Happened both ways.) Staff was friendly. Boxed water tasted weird (a little like cardboard?) but not a huge deal. Overall good experience.

5 hr flight with no meal service is just unacceptable. We got pretzels and a drink..

Although delayed an hour, the gate attendants kept us notified and the rest of the trip went off with no issues.

We showed up to our gate less than 15 minutes after boarding started and they wouldn’t let us in. It was still 15 minutes even before take off so we’re weren’t even late to the flight.

Flew first class. No headrest screens on either flight and the one flight had no foot rests either.

Someone rebooked my Alaska flight to a much later Delta flight. Now I am sitting at the Seattle airport after a long international flight and have to wait another 4 hours even though I would have been able to catch my initial flight

Eva Airlines attendants were wonderful. I really enjoyed the hot meals. They always greeted me with a warm smile. I'm looking forward to flying back to the USA with them again!

Flight was cancelled which destroyed the rest of our journey.

WOuld have liked coffee or pretzels but other than that, crew and pilot and flight were great. Seat was great, too.

Great experience. Boarding was fast, staff were very nice and funny, everything at the seat worked well.

Boarding was great, and the crew were very friendly. The seats must have been a bit on the older side and you could feel some of the seat components through the padding. Also, the plugs did not work on the row's entertainment screen or charging ports. Checked bag was transferred for connecting flight, and we appreciated how early we had the connecting gate information.

Lost one piece of luggage even though I checked in 2.5 hours before the flight

It was Swiss. Our kosher meals were literally frozen solid and therefore inedible, and the crew didnt care.

For the expense of first class, the seats could have been nicer and higher tier snacks would have been nice.

The boarding process on the departure from LA was rather slow even though I was in Group 1. For first class, I was not expecting to have to pay for Wi-fi but I did and then the wi-fi was spotty. The entree was surprisingly good and so that was a pleasant surprise. However, once I got to Houston, it was terrible. Unfortunately there was bad weather but the constant gate changes for my connecting flight was difficult to manage due to having to navigate back and forth between different terminals.

We used Kayak to reserve our tickets and specifically checked the luggage option which was a more expensive option. When we arrived at the terminal we had to pay an extra $90 per suitcase for the three passengers. This has been a pattern for the past 3 years. Why charge for a more expensive luggage option, and the ticket price not include luggage?

They delayed the flight 3 hours because it wasn't full they moved us to 5 different gates probably the worst airline ever not even spirit is this bad.

Very easy ! Use the kiosk and bag drop and right to security within 10 min

Checking bag at terminal was horrible. No agents to check us in and only 1 kiosk working. Boarding went ok. Crew onboard was very scattered rained. Missed our row while serving and then didn’t see them hardly again.
