Flight was fine. Only thing was flight was delayed nearly 2 hours. Flight was originally scheduled to depart at 7:50pm but didn't depart until 9:50pm. I got home around midnight. It was later than desired and I had to get up early next day to take kids to practice. I have noticed that last flight of day on West Coast for Southwest always tend to have delays.

Terrible delay today. also, waited 90 minutes for baggage to unload in Seattle earlier in the week.

Seated at front bulkhead for a smidge extra leg room away from home and on flight back home. Away crew was very proactive about assuring our carryons had space close behind us (because no seat in front of us our personal items had to be in a small bin overhead). They actively required passengers place overhead luggage on its side so more items could fit in bins. Home crew made no such efforts. I had to struggle back rows to get overhead bags upon landing, no crew help then either, and some disgruntled passengers as I and others retrieved our bags. There was a system that worked pretty well. The home bound crew just didn't feel like working.

Flight left on time and was early landing. Seats not comfortable and not enough space…

It would have been better if the flight was on time

No wifi, seems to be very common with Southwest currently. Everything else was normal.

Poor customer service, no accommodation for passengers when the flight was delayed over 5 hours.

The flight was late. The crew was rude. There was no food. Cramped and uncomfortable. Nothing about this flight was good.

It was just okay, no frills, basic transportation with no luxury. No screens on the seats, no water or drinks on a short flight. Full flight but at least it was on time.

Boarded the plane in Portland and sat on the tarmac for four hours before being given clearance to take off. Apparently a "scratch" was detected on the preflight inspection. This delay resulted in me missing my connection in Baltimore. I therefore had to stay overnight and then catch an early flight this morning, which resulted in my missing a mandatory class. I would like a refund / voucher to cover the cost of the missed flight. And additional voucher for the time spent on the plane in Portland would also be appreciated.

great! appreciated the last minute upgrade to Comfort+ exit row, as well

My seat was changed without my consent. It wasn’t a major deal but annoying.

The Airline Attendant found us in flight and moved us to seats in the front of economy due to the short time we would have to make our connecting flight. We really appreciated it.

DL486 could not get to the gate due to jet bridge malfunction. We moved gates. The connecting flight of LAX to MCO was not communicated with. Even though we were in the same terminal, DL482 left without about 10 of us, including a mother and her 3 children. I got to the gate at 7:34 am which is past the 7:20 am last call for a 7:35 am departure. Had they waited 5 minutes, all of us would have made it on board.

Delta has joint the nickel and diming airlines. The experience is getting worst by the day. 1,000,000 miles for a trip to Asia in Business Class where I got the same thing for just under 90,000 miles through an Asian airline. Where is Richard Anderson? Please come back!

Very bad multiple confusion and miscommunication which i ended up missing my flight.

The experience was bad. Flight was delayed to handle maintenance (understandable) but still there was some dew forming and dropping as droplets on few seats. Internet at best was allowing some browsing but at a snail pace.

Both of my flights to and from JFK experienced significant delays. Most notably, my first flight was delayed by six hours due to crew members being affected by delays on a previous flight. While I understand that disruptions can occur, Delta’s staffing and operational planning should include sufficient contingency measures to handle situations like this rather than placing the full burden of those delays on customers. Additionally, the $12 meal voucher offered as compensation was inadequate, particularly given the high cost of food and beverages at the airport. Considering the length of the delay and the substantial inconvenience caused, I believe more meaningful compensation would have been appropriate.

Comfortable seats. Nice service online. Short flight, so not a lot of time to enjoy.

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

The food was horrible. There was no. Wifi, and it was just terrible from bangkok to d. C

My flight got cancelled. Couldn’t get my luggage. It arrived at my destination ahead of me. I didn’t get my preordered meal. Had to spend the night in the airport.

United did nit provide any updated on flight crew not bein available until boarding time started. It was bad. Itws alate night flight and there no proactive communication and iha d an important meeting that i missed due to thus

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.

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

Even though the incoming flight was delayed by 20 minutes they managed to get us to SFO 15 minutes early.

Boarding, time to take off, in flight offerings, and staff were all great. I recommend using UA for this short flight.

The flight out of Fresno boarded 1.5 hour past scheduled and made me miss my connecting flight from SFO to SEA.

Airplane is not very clean, food quality and taste was not good. Lufthansa used to be good but nowadays went down. Overall experience is just okay, wouldn't fly again, prefer Turkish airlines.

They changed my flight 5 hours before it took off and changed my connecting airport messing up my entire 1st day in Japan.

The guy sitting in front of me kept pushing hard his sit against my legs… very uncomfortable

Food was horrid. In my opinion inedible. They did offer some sorbet and one small dish of fruit. Stewards were super stingy with water, coffee, etc.

On-time, direct flight is great. Having one bathroom out of order was unfortunate.

I am absolutely furious with American. they shut the door in my face when I was trying to board the flight and kicked me off of it. They made no attempt to call my name or contact me or anything. They just said they gave my seat away. The customer service response has been atrocious. I will never fly this airline again as long as I live.

The WiFi was out gr entire flight. Had to Diane for almost 1 hour to wait for a gate to open up for plane to dock. Very bad experience.

Not too much it was pretty good all the way around

American Airlines put the food on the wrong plane which had already taken off by the time we took off so we had no food on the plane.

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

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.
