Surprisingly the coffee was pretty good and they had a gluten free bar handy!

Surprisingly the coffee was pretty good and they had a gluten free bar handy!

Gate agents call groups one and two and give about 3-5 minutes for each group to board, then the call groups three and four together and it causes a bottleneck in the line. Give each group 3-5 minutes to board before calling the next group.

We sat at the gate for over 30 minutes, with no indication as to why

I didn't really interact with any of the crew since we had a bumpy ride and no refreshments were distributed.

It was delayed over an hour and a lot of announcements disrupting movie.

I didn't use the onboard amenities, so it is difficult to comment on those services. Otherwise, the flight from Nashville to Toronto was quite crowded, but the boarding process and the flight itself were perfectly fine.

Seats were old and very uncomfortable. Coach seating is way too tight

WiFi was a major problem and if it does not work on a 4 hour flight then that lowers the overall experience

The wifi was barely operable. just enough to charge me, not enough to be useful. I wasted 2 hours of time I could have been working. So now, I' have two hours of work this weekend to catch up on thanks to Delta's crappy technology. Plus I'm out the money!

Delta did an awful job w logistics at DTW. Missed connection. We were there an hour early. SUCKED

Smooth flight, easy boarding process. Made up time in the air with initial delay due to weather pass through

Usual wait for over a half hour for a gate at Ohare. They tell you you'll get there early then sit on the plane and wait almost an hour

Plane congestion resulted in a 1 hr wait from landing to arrival at the gate. This was in addition to also experiencing extreme delays on my incoming flight.

Delayed too much. 1.5 hrs in the airport and another 1 hr in the runway. Got too late in the night. There was no proper food available.

awesome team work seen since on board till off plane in my destination. thanks you so much.

Job well done, being treated for good and helping a lot . thanks you so much till will meet against.

Very disappointing that on an international business class flight they would not give me access to the lounge in Boston. They said it was because it was a codeshare flight. International business class should include lounge access regardless of codeshare.

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 crew was wonderful, the plane was fine. We left the gate on time, but we had to wait 40 minutes on the tarmac because of all the congestion at Boston.

ontime. Seats are terribly close together for someone my height.

Both directions of our trip were befuddled by massive delays, one of which led to our connecting flight being grounded mid air due to storms that we’d have missed if we were on time. The other our originating flight was delayed repeatedly until it arrived at our connecting airport later than our final leg was even supposed to have arrived. American cannot seem to manage rebooking s for a family party… both directions we had to come up with a plan to get to Boston stay overnight only one night each direction was covered by the airline -and take a bus to or from our destination. Missed an entire leg of our trip, hotel cancellation fees, expensive stay in Boston and bus ticket expenses are unlikely to be comped and the meal vouchers are worthless.

My flight was 4 hours delayed on departure at 6a causing me to miss my connection at DCA. I had to scramble to find a seat home on a later flight and instead of an exit seat, I was in row 30 on a flight getting me home 5 hours later than planned. The AA team on the ground did a fine job. AA continues to run the airline like the passengers are cargo.

The flight attendants were very friendly, efficient, and helpful. The plane was ahead of schedule, and it all went very smoothly. Thank you.

I have a gluten allergy so did have any food

The plane was probably full boarding was easy. We were able to check our carry-on luggage for free. It was a return flight through Philly to LA. Never saw a stewardess do a demonstration of emergency Procedures. I think my flight was pretty full

Wonderful crew and early arrival to our destination. It was so nice to have free wifi access and movies too. Thank you!

Flight was delayed after boarding and no idea when it would take off. Crew in Portland did arrange for transport to Boston for a different set of flights to my destination.

Seats are so close together. Middle seats should be discounted.
