As an Elevance employee, don't we get priority boarding? Also, I boarded zone 5 and could not get normal carry on in luggage space. There were many Delta employees on the flight and their bags, which were large and could only fit two bags per compartment, got preference over customers so I had to check my bag.

Everything went smoothly, WiFi connection was strong. Time to upgrade the regional planes, we are all on top of each other. No room to comfortably do anything.

The bathroom is disgustingly dirty. It looks like the crew members didn’t clean it on a regular basis. Also, who made the bathroom so small?. I am not a big girl but I still feel very cramped inside. Def unpleasant experience to use the bathroom.

My experience with Delta is always pleasant. My return flight #1426 from ATL to RIC was very delayed with departure and landing. It also took a substantial amount of time for baggage claim. It was already late at night, so the delays made for a very long day. I did not get home until after 12 midnight.

I had a great flight with delta. Plane was clean and the staff was nice, I would fly again with delta.

After flying with Qatar Airways and Kenya Airlines. Delta leaves a lot to be desired

A 6hr delay is going to put a damper on all reviews. It was almost impossible to get into the Delta club also. Zero conveyance. I could not use my status for anything. Makes me wonder why am I loyal to delta?

I fly coach so there is always the feeling everyone up front has more space than me. Everything was fine - on time which is the most important thing!

Great overall experience and use of the Delta One lounge was amazing!

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

It is completely insane to me that first class does not include WiFi. Also does not include lounge access. Port for phone charging did not work. The crew was absolutely lovely, and the food was excellent.

I appreciate how quickly and kindly the people at the gate at DCA accommodated several of us who wanted to switch from the 6pm flight to the 5pm flight at the last minute. The flight crew was helpful to us too (dealing with luggage).

Very uncomfortable and cramped seats. Everything else was okay, the crew members were nice but nothing was exceptional.

Check in went smoothly. Flight attendant who was assigned my area barely paid any attention to me! She acted as though she was extremely busy and flustered. Maybe she was new?! I told her to change the language on my screen, she said she’d come back to help me but never did so I was able to solve the problem on my own. She came back and said she’d made adjustments on her end. Highly doubt it because I found the setting to change the language! Also, I noticed everyone was eating before we landed so I pushed my help button and she never came so I got up to find her to ask her if I can have breakfast. She said they are not serving breakfast but I can have a sandwich. Yes, that was her response as I saw everyone eating breakfast!!!

United staff were very communicative, the new starlink Wifi is amazing as I was able to work easily.

Starlink internet made the flight time shrink and I was able to work.

Seats are made for children. An 8 hour flight with tiny seats is more like a cattle car. Lost bags at Rome airport caused a 7 hour delay.

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.

Flight was comfortable- just had to endure a 1 hr delay because of some maintenance issue. Happy that American Airlines does these final checks but just wish they would conduct this maintenance before the flights.

All good. Flight crew was super friendly at the end of a long day

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.
