Flying into PAE was so easy because it’s baggage claim is quick and accesible. I had a car rental and the counter is inside the baggage claim area, very convenient.

Flying into PAE was so easy because it’s baggage claim is quick and accesible. I had a car rental and the counter is inside the baggage claim area, very convenient.

Crews were friendly enough. To help the airline I checked my carry on baggage. Typical "gonna be a full flight we need 19 carry on bags to be checked to help out". So I helped out only to have to wait 30+ mins for my luggage and risked not getting to my car rental on time. The return flight was delayed. Kept hearing employees say something about "they didn't have any power" which is kind of concerning. The air flow and air conditioning was insufficient. It was warm and stuffy during the flight. Plus no free wi-fi......Booooooo!

Great trip. No complaints. Impressed with the crew’s response to various challenges pre-boarding.

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!

Very terrible/ never will I fly this airline again. Poor service in the plane. They cancelled a flight without booking another. All the way around it was too awful.

The whole staff was amazing. Courteous and so helpful. Smiling all the time.

Flight maintenance was on so that flight didn’t go able to fly out to Seattle and Inhad to get another flight,,

3 of the 4 legs of our trip the crews were awesome! 1 leg the trip attendants were rude & dismissive, didn't even greet us when boarding even though both myself & my husband said hello directly to them when we boarded.

It was a very short flight so there really wasn’t any entertainment my. The little pretzels were good though and the cabin crew was awesome.

Well organized boarding. Cabin crew were efficient and professional. Thoroughly enjoyed the flight.

Lounge was top notch h with great variety of food and drinks. Cabin crew were great. Smooth flight.

Seating and zone. The minor I went with didn’t even seat close to me

My seat 3G did not go down fully and the buttons were not working properly

Food has been disappointing in both legs of flight to india

Great staff great experience, made a 2 hour delay very bearable

Great staff, great experience, made a 2 hour delay very bearable

Food was the worst I’ve had on a VA flight. Normally it’s a lot better

I was my pleasure to fly virgin on my birthday for my first solo trip ever 🫶🏼

These are one of the older seat arrangements facing away from the windows! Not particularly convenient sets. No storage spaces. NO COAT HANGING HOOKS. Inconvenient business class seat compared to any other airlines of similar class. Staff are excellent! Extremely professional, friendly. Food is good too.

Overall, flight was excellent but check in was very slow for Premium Economy. Economy queue was shorter but we weren't allowed to use it.

We paid for saga class, which is the business class for international. My seat was broken and did not recline and my monitor for in-flight entertainment was broken.

The flight itself was fine, even with a one-hour delay leaving on the Reykjavik tarmac (the lost time was made up during flight). Our experience at the Reykjavik airport on arrival was terrible due mostly to the one hour it took for passport control. Only two stations were open for our category, and the room was full with a huge crowd.

I liked the crew but not the uncomfortable seats and lack of movie and tv selection.

They cancelled our connecting flight resulting in another layover reaching our final destination 8 hours later than scheduled.

Awful. The Iceland airport was a complete mess. Boarding was a chaotic, the seats were awful, there was a group of rowdy 20 something men in our row hooting and hollering, ordering alcoholic drink after drink. Yelling and laughing at the top of their lungs and the crew just went along with it. Passengers complained to the men, asking if they could keep it down (it was a night time flight so people wanted to sleep). They never listened crew continued to laugh with them, flirt with them and serve them more drinks. No free food or snacks, seats were horribly uncomfortable. Worst flight I've had in a long time

At least one soda free, felt like I was nickeled to death.

Friendly flight crew. Airplane (757) configured as a domestic flight (no lie-flat seats) & no advanced meal selection.

Was a bit surprised that Icelandair flies a domestically configured 757s on long-haul flights to Iceland (no lie-flat seats in business class).

The Icelandair crew was so kind!!! Thank you for making my first trip to Paris a great one!

I am not going to fillo this out for each leg of my trip. My first review holds for the experience

Seats not as comfortable as I had hoped. Food was very nice, service was fine. Entertainment options very nice. Had thought the premium economy was a more plus 2-3-2 layout but it was a 2-4-2 with seats not as wide as I had expected.

I flew four flights on British Airways within two weeks. I was unable to download the boarding pass to my phone for any of the four flights. I could check-in for my flight but the system would not give me boarding pass. I tried multiple ways and multiple times. I discovered many other passengers also had the same issue with their boarding passes. No explanation or acknowledgement by BA.

Lovely big plane. Excellent take off and landing. Cabin crew were so nice. Flight in time no delays

Because our ABZ-LHR flight was cancelled by BA for reasons they refuse to tell us--not weather--we did not make this flight and were booked on the following day. BA offered no assistance to us on the phone or in the airport, and we had to find a hotel at Heathrow on our own.

Horrible - flight was delayed by 6 hours - we boarded, were made to de-board due some technical fault; aircraft changed; special meals request on new flight - all went awry. Landed in Dulles airport; breezed thru immigration; as Business Class passengers or baggage was delivered almost 90 minutes after landing; air tags indicated the bags were just near the carousel but the unhelpful BA staff - Maria and Ghina refused to give any update - palming it off on some imaginary invisible “manager” despite air tags evidence showing it right there. So about 50-60 passengers waiting and getting infuriatingly impatient for their bags coz one container was not delivered. Finally after much argument by some other passengers Maria condescended to go to the “ramp” and within 5 minutes the baggage was delivered miraculously. Question is why couldn’t she have done it one hour earlier ? Poor poor experience once again on Business Class BA.

Cheap Flight Fares would not provide booking info. I canceled the reservation and we arbitrated with American Express. They provided erroneous info to Amex and it was determined that C.F.F. deserved the price of the ticket. Worse experience I've ever had.

Seating space is appalling. Seats and all surrounding area in "Economy" is built for individuals shorter than 4' 10" and below 120 lbs. Ridiculous. While I'm not expecting fine dining, the food was the worst airplane food that I can recall.

Business class lounge for my gate was closed and no email was sent, causing me to walk back and forth to different gates, etc for over 20 minutes one way. Flight entertainment was mediocre with very poor choices especially for business class cabin. Original flight was cancelled and rebooking was difficult and no reason given for cancellation.

Very comfortable flight and simple and directed one way and back. Amazing price.

We loved our flight attendant, Emma from Scotland, the meal and entertainment offerings were wonderful, the flight was smooth, and enough leg room to stretch. We would fly with you again!

Great crew. Food was pretty good. Seats are narrow and internet is expensive

This Condir premium economy is terrible. All it is is a few extra inches of legroom in an economy seat. British airways premium economy is the same as a first class domestic seat, wider with more recline. Plus the flights were all late to leave, arrive, etc. terrible day.

Absolutely the worst food I ever had on any flight. Half of passengers simply didn't eat their meals, as I noticed.

Food could be better. Service was just ok without any enthusiasm...

The breakfast snack was horrible. No nutrition value. I couldn't finish it. The main meal had no taste, no real vegetable, the brownie had no chocolate taste., I was not even sure what the salad consists off.

Breakfast was terrible. Sugary yogurt, inferior pastry, poor quality fruits. No protein.

Our connection in Frankfurt was the worst ever. No one from the airline or the airport seemed to be bothered to get us into our connecting flight on time! The procedures at the airport took us forever and we barely made it into our flight. If we had missed it, I’m sure we would’ve missed our cruise. Looks like everything is on autopilot and no one is interested in helping customers anymore especially us 69 year olds

Crew was very responsive to give soft drinks etc.. At Frankfurt Airport Special Assistance did a great job for us. The seat cushions were simply bad and not up to the mark for Premium Economy which we chose. All the cushions from Business to Economy were poor. Also, any snack besides lunch and breakfast, you have to purchase including chips and chocolate. It is simply cheap. I don't think I will fly Condor anytime soon

The short leg flight was fine. Crew and airport were nice to allow special assistance which helped.

Planes are new and clean and staff is attentive. Food wasn't great and chair cushions were very uncomfortable for long haul flights.
