I sat in comfort plus. It was fine. Seats were comfortable. I got drinks and snacks.

Crew was nice. Flight was timely. Seats could be better as well as the food considering it’s first class.

Left on time and arrived early this extending our 31 minute transfer. Bags made it also!

Good and consistent Printer in lounge did not work for me :(

Most of my discomfort was going through TSA. However, the Delta seats had inadequate leg room and I tried my very best to connect to the wi-fi and it was a cumbersome process that finally gave me the info that I needed to sign in AFTER I had completed the flight...Why make it so difficult to use? That said I really really appreciate the pilot taking a little extra time to avoid a bad storm area and both landings in Atlanta and Orlando were flawless to my delight!!!

Delayed in taking off because no flight crew. The in seat entertainment was working properly.

All fine save for the abominable catering. Really gone downhill. We found it all inedible.

Bottom seat cushion is almost non existent. Very uncomfortable seat.

Coach seating is debilitating, neither my husband or I can walk the following day

It was NOT pleasant. Started from checking our luggage to the last time getting off the plane. The crew was not friendly, the food was horrible and the seats were too close to each other that I got a bruise on my knee.

Finding the gate was very confusing. Our boarding pass listed one gate and the staff verbally told us a different gate.

Plenty of overhead space but forced to check my carry-ons both legs

My flight attendant was attentive! The elderly person next to me was flatulent and the flight attendant could see that I was in distress and brought me some face masks

It was as expected for such a short flight. No complaints

The departing flight from Newark to Charlotte was fine. It was the returning flight from Charlotte to Newark that was awful. We had scheduled an 8:35pm return flight time. We got delayed TEN times all the way to 5am in the morning! We were told over 4 different excuses as to why the flight kept getting delayed. First it was the flight crew needed to rest, then it was something technical with the plane, then it was something with air traffic control, and finally it was because they couldn’t find a captain and had to wait until the morning so the captain could get some rest. It was terrible sleeping overnight in the airport. They offered a $12 meal voucher. That was it! And the only place open in the middle of the night was Dunkin’ Donuts who didn’t even accept the voucher. They should have cancelled the flight much earlier on in the evening instead of just stringing us along hour by hour with more delays. Not professional and unacceptable. There was no refund for inconvenience. I probably will not be flying American Airlines again.

This leg they tried and did well with what they had to work from.

It was nice being on a flight that had working wifi. The boarding was quick - why don’t all airlines have small boarding groups window to aisle? Makes so much sense!!! I was disappointed to be the first person stopped to have to gate check my carryon. Especially when there was plenty of overhead space at the back! But I get it…keeps it moving. Crew was nice.

The flight was as good as it gets when flying. On time departure and arrival plus no lost luggage.

My boarding pass wouldn't pull up in the app very easily and had to really dig through my email. That caused a delay in TSA..

Packed commercial flight was as comfortable as can be expected

Icelandair flight was excellent. The checkin and security arrangements for Saga Premium passengers at Newark was very poor - our checkin opened much later than the normal and our security queue simply led us to the back of the normal queue. Someone was having a laugh surely!

Never took flight. See previous comment on trip from Boston to Reykjavik. Used a different airline that i had to find and book.

The flight was on time and the crew was nice. I did not like the fact that my husband and I were seated in different rows. I feel pressured by airlines to pay more to choose our seats. We will sit anywhere, but we shouldn't have to pay to sit together. I also think they should serve at least a snack that's free.

My only area of issue was the flight was rather warm and the knobs for cool air didn't allow much cool air to come through. Everything else was great.

Everything was great! My only critique is 25 euro for wifi is wild, but I get it

Good, but I feel there should be a separate boarding line for seniors

Easy check in and boarding. Staff pleasant and helpful. Will continue to fly with Iceland air. Aircraft clean

Plane left an hour late and missed our connecting flight. Your service center was closed ao Alaska Airlines could not change the ticket. Thus we missed the chance to get out that night to San Jose. This is a major operational blunder.

Well! They got me as far as Iceland, let me wait around at the airport since my next flight had either left or canceled, finally gave me my luggage, and sent me to wait quite some time with seven other people for a ride to a hotel. At the hotel we got a chef's salad, a nice room for the night which unfortunately had feather pillows and duvet (allergies), a really great and spectacular buffet for breakfast (small but stunning), taxis back to the airport for the 9:30 Delta flight back to Minneapolis. The Delta flight has free food and liquor included which Icelandair does not. All in all, it falls far short of my worst ever United flight to SGN. Icelandair did change my reservation after my roommate tested positive for COVID and we canceled our plans to travel around Iceland, but the charges were fairly hefty. I had trouble contact Kayak's agents to discuss changing my reservations and finally contacted Icelandair who changed them. (I used their contact form and put in several requests for call backs.) Of course, they called just after I made the change with Icelandair.

Flight was delayed. They did a terrible job rebooking me. Agent on the ground was useless. The partner airline who ran the plane was able to help me but Iceland air was useless

Republic was fine but Air Canada was terrible in the airport. They issues me a boarding pass that I placed in my wallet and then when I showed up at the airport they had taken the bar code away from the ticket because they changed the flight number even though the flight stayed the same time. This caused me to be unable to go through security and I had to go to Air Canada for help and they were horrible and almost caused me to miss my flight. Luckily I managed to get it figured out on my own phone, not the kiosks, or the agent I asked for help or the long line I was standing in!!

Flight was fine. Arrived on time. More room in the seats would be nice, but not something that is likely to happen.

Unfortunately your planes need maintenance. I am surprised your bathroom in business class was not working in 8 hour flight. Coffee machine was broken. Seat adjustment panel was bad. I will stay away from Air Canada in future travel.

I was in Business Class row 7 on a 787-9. Both times I didn't get my choice of food. Otherwise, excellent!

Problem with operation of on board entertainment computer. Failed about 1 /2 hour into the flight. Rebooting failed to restore.

Putting carryone size suitcase into the overhead luggage storage on a the small CR900 plane was cumbersome and its assignment to a far far gate w/o the moveable ramps at YYZ arrivals really stunk.

This flight was a lot more comfortable with more room than the Air Canada Rouge!!! We will never go rouge again! A yes to this one!!! It was so nice to have inflight entertainment! Also the carts came around twice for drinks or a snack!! Great experience all around!

AC flight attendants aren't overly friendly. Otherwise flight was fine.

Newark to Montreal was really good. The return flight was not so good with a substitute carrier was not as good. I was impressed by the AC staff all along the way. Their in flight stack was superior.

I’m handicapped and the staff and crew were so kind and helped me board and made sure I was fine during the flight.

Great job notifying of 30 minute delay in departure. Fabulous job making up for the time and arriving as scheduled. Air travel is just no fun anymore with the extreme overcrowding, and someone needs to come up with an innovative plan for loading and unloading passengers (load all window seats first, middle seats second, aisle seats last?). Great job getting the luggage on the carousel in record time!

Although it was an overnight flight, the crew could’ve have made more refreshment passes.

All and it was good . But no one woke me when meals came around . Please have a don’t not disturb sign if you opted for that . Left very hungry missing all meals .

It was good but I wished if they could have sign do not disturb if we did not wanted any meals . I was tired and slept through the entire flight and woke up just before landing .being hungry Too late to ask for something to eat before exiting the flight . Left feeling hunger 🙁

Late in leaving the US. Late in arriving in UK. 2 plua hous on ground in UK before leaving. Late in arriving in Spain. Didn't get our bags until the next night.

British Airways canceled my flight and I had to fly on Lufthansa the next day. What a garbage airline 🗑️

3 hr delay. No water given while on the plane for 3hrs.

No fast track available, no organisation. Unpleasant boarding system at gate 20 at JFK. When giving feedback to the lounge team I was told to talk to the manager instead of taking the feedback.

The whole experience was great. The only improvement would be the entertainment selection

Flight attendant kept banging her cart into my aisle seat. Hard. Couldn’t lean seat back. Should be warned of limitations when booking seat
