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.

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.

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.

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.

It might not have been their fault, but there was a two hour delay due to weather. Then we boarded and were about to leave when they said there were more problems at the destination, took us back to the gate where we had to fully deplane. But then five minutes later, they said everything was fine and to get back on the plane. This was the part that pissed everybody off.

Comfortable seats, good drinks with lots of water refills, staff was kind and understanding of my disabled mother!

They were flexible and able to get me home a day earlier due to a family members illness. Flight was on time and great friendly crew.

Agent could not provide me a boarding pass for the second leg of my flights - yet with a partner airline. Not understood.

The crew was great and everything went smoothly coming and going.

They were friendly, efficient and got our bags to us so fast at the end of the flight.

Nobody’s fault but turbulence all the way meant no service and no access to the bathroom,

Be on time? When not on time a circling for over an hour offer more than 1 bag of chips to the passengers? It was a 7 hour flight by the time we got done.

Long story short, it was one of the better flight experiences I've had in some time when compared with other airlines.

Generally on time departures and arrivals, clean planes, sky miles membership provides great benefits (complimentary upgrades, etc).

N Everything was perfect from boarding to assistance to baggage in Tampa

Fast, lovely scenery, great info on the Delta flight screen about landmarks we were flying over. Great landing!

Long flight but comfortable and not freezing as I have experienced on Hawaiian flights to the islands. They gave us blankets just in case. Nice touch.

My recent experience was excellent on Delta! I flew with Delta Comfort and I was really comfortable in my seat. I enjoyed the in-flight service. The flight attendants were so friendly and hospitable. I love the snack on the flight as well. This was my first time flying on Delta and I will definitely consider flying with them again.

My flight was canceled on Sunday. Rebooking took three hours. Had to pay for accommodations another night. New flight was delayed for 5 hours, all that was sent was a 12 dollar food voucher, which doesn’t tell you how to use it. Then when we landed we had to sit on the plane for an hour before we could get off.

Flight was delayed by 3-hours and their fix was… complimentary pretzels.

The crew, and fellow passengers, were super gracious and kind. There seemed to be plenty of bin space even though the plane was full. It’s nice to get a glass of wine with dinner in Premiere seating, and there was a lot of food.

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.

Flight was delayed but more than 90 minutes. This caused me to miss my available windows for pick-up by a friend. I had to pay $125 for an uber back home from the airport which was an added expense that I had not budgeted for my trip. Staff was friendly.

My flight was canceled a few hours before boarding. I was rebooked on Copa airlines and missed an important meeting .

OK, we were delayed and had to de plane and reboard.

Crew was great (professional, attentive, prompt). Snacks for 4 hrs flight is deplorable.

I’m so sorry, I can’t remember her name, I believe it was Dimpti. She was stellar, also a mature Asian flight attendant, lots of flowers in her hair, just as amazing! But literally the crew was AWESOME . Only downside is there weren’t any charging outlets. Maybe I needed to ask a flight attendant , but it would’ve been nice to have one easily accessible.

The flight attendants were great, I joked with one I can’t remember her name, a blond, really sweet. I thought it was run well very professional. This was great i survived Spirit, I know for which I speak.

United sent me a mileage plus number last year but that number is invalid so I can’t use it to check into flights or collect mileage. There is human to speak about the problem, only computers who keep asking me if I am using the correct email. It’s so frustrating and I cannot resolve it.

it was so bad. I tried to board my flight from vancouver to saskatoon. And to my surprise they did not board me cause the flight was changed and no email was send to me. and on my boarding pass which i got from seattle says different flight. I did not knew anyone from Vancouver, air canada crew was rude, i asked for today flight but they were rude and i had early morning dental appointment in saskatoon. I was so much in pain and my whole day is wasted today. and i suffered alot. They did provide me hotel but they did not provide me any food. I am really really disappointed first time had so bad experience with air canada. I may think twice to book it again. If i can get any reply or any composition that would be great. Thanks

The gate was too far away for the connecting flight
