Didn't buy food and did not use entertainment as these were not the purpose of my flight.

Didn't buy food and did not use entertainment as these were not the purpose of my flight.

Website could be better with faster access to specific flight information and boarding pass once reservation is made. Not a fan of no seat selection on line. I had to consult gate agent each time to change seats on flights with lots of open seats. This cannot possibly be cost effective for airline. On plus side, Alaska seat legroom seemed larger than American. ns

They offer the only direct flight from Seattle to Pittsburgh.

Staff inside Portland terminal were rude, made us fell rushed and not at all accommodating to seniors. For this alone I will probably never booked from them again.

It was fine—the seats are not very comfortable and the aisles are very narrow. Nothing different from other airlines

I booked a round trip. I ordered a lunch going and a lunch for the return but got both lunches going. Could have been my error. Both lunches were good.

Well the flight being delayed multiple time really was frustrating. But the crew and flight was good.

generally good. No snacks or drinks on the flight 3379 from Portland to San Jose, CA. Sad.

Everything except for the lack of a choice of the snack provided was great.

All went smoothly. Only one delay departing Seattle of around 30 minutes.

The staff and the boarding procedure were all amazing . The one flight was not equipped with WIFI which now adays seems odd. All in all the experience was good

Perfect flight both ways. On time, courteous staff, plane comfortable and cool. Best domestic flights I’ve had in awhile.

Really low quality food especially for an international flight. The crew also was surprisingly unpleasant except couple of ladies. I know we were not in first class but that’s no reason to treat customers as less.

Flight delayed for two and half hours and then canceled altogether due to mechanical issues. No mechanic onsite to fix so had to send one from LAX.

Crew was good. The reservation got mixed up and they didn't have my TSA number. I am also a Silver Medallion and wasn't able to use Sky Priority.

Delta made it easy, comfortable and timely. The crew was fantastic.

This route with Delta always has delays or is cancelled. Aircrafts seem smaller and older. I fly Delta quite a bit - haven’t had issues with the international flights. But this route has always been the troublesome one

Three seats in first class were broken and while they were able to still acommodate us it was looking very touch and go and they had others they could not acommodate

Mechanic delay in addition to a 2 hour change in takeoff time was frustrating.

Delayed due to thunderstorms and no in-flight service due to rough weather — both of which are out of Delta’s control. Flight was good overall.

Terrible. They wouldn't allow me on my flight on the 14th..

The newer screen was super cool and had the option to watch many different shows or movies. Crew was polite and helpful. However again, many children screaming bloody murder and kicking my seat, and parents doing nothing about it as usual.

Flight was good and crew was super polite. However, there were around 5 kids screaming the WHOLE 2 hours. I understand kids have to come but parents need to do something to control their children. They make the experience terrible, especially after finishing 16 hour shifts at the hospital I needed some sleep, which I did not get.

IAD with the archaic people movers is just a place to be avoided.

All of the United employees I interacted with were professional and courteous. The aircraft was clean, the food on the flight was good. No complaints here.

Armrest controller on my seat 35D and nextbooennseat 35E did not work right. Hard to press buttons to recognize and 35D had constantnpressure either upmost down somit was nearly impossible to make selections. .

I flew with my dog and had already purchased my dog’s ticket. Even that morning I had called costumer service to insure that my husband and I had seats together since the website was giving me an error when choosing our seats and the representative mentioned our dog. I showed up early to the airport and when I got to the gate and we started boarding I was help back and told that I was supposed to have a yellow tag and that I should have checked in at the counter for them to give me that tag. I was not aware of this, the representative on the phone did not say anything. Nor did I see it anywhere in the checking process online, so if you travel with a pet and are not checking in luggage, just know that you still have to go to the check in counter when arriving at the airport unless you want to be the last one to board and not have room for your carry on in the overhead bins. Other than that, I had a great experience.

Once we got in the air the pilot made up some of the time of the delay. So that was really nice.

I understand stuff happens, but plane failures are likely due to lack of maintenance. Additionally, air conditioning wasn't working, no snack/drink service, no WiFi. Fortunately, the crew was communicative and light-hearted. United grabbed another plane and we were able to get to our destination.

There was no food available for this red eye... one little waffle cookie for a 6+ hour flight... thank God I was able to sleep some

Internet was a bit expensive and did not work ask that week otherwise a good flight

The flight had a delay that made me being in a real rush to take the second flight. The delay was almost for 2 hours. They moved us from gate to gate in 4 times. Once I arrived to Philadelphia, I got to run thorough all the airport, as the train was already closed by that time. So I got sick with asthma for all the running I had to do. And I was the last one to board, when it was almost closed. So irresponsable with the people

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

Overall, a good experience. The food, however, was subpar. The breakfast was a joke.

I was late from Jacksonville, FL but the limited interaction I had with the Philly crew was great.

The delays and cancellations kept me stuck in Miami for an additional 24 hours, and the whole thing seemed extremely disorganized

Everything was great except British airways lost our luggage that was gate checked all the way through to Italy. No one knows currently where one is and the other one may be in route to Amsterdam to meet us but not sure. If you can Hale’s it would be awesome. The website is not helpful.

Wonderful as usual except for other guests that were unruly and not kept in check by the Crew.

This was an overnight flight. There was no meal service in first class, just a simple snack basket was offered along with beverages. There should have been some type of continental breakfast prior to arrival in PHL. As an Executive Platinum American Airlines Advantage member, I received no name recognition from the first class flight attendant. When disembarking at PHL, the flight attendants were more interested in their cell phones than saying "thank you" to the passengers as they disembarked.

the pilot that landed this flight in Philadelphia did an amazing job, the weather was absolutely terrible and we landed safely.
