Top 5 airlines serving from Washington, D.C. to San Diego
I was seated at the back of the plane and the flight attendants were fantastic. I did not get food so can’t say. Thought the movie selection was lean.
I was seated at the back of the plane and the flight attendants were fantastic. I did not get food so can’t say. Thought the movie selection was lean.
the departure got delayed due to SJC situation, but it was a quite good waiting thanks to Alaska airline teams.
The flight attendant in the back of the plane was barely understood as she rushed through instructions to the point of being intelligible. She had a bored demeanor in her delivery.
Staff seemed genuinely nice, not just going through the motions.
The pretzels are awesome. The free movies are excellent. The plane crew was amazing. The Austin airport lounge was too small and overcrowded. There were not enough seats. And the boarding staff was not as friendly.
I like Alaska Air fine. Great crew. Late departure still arrived on time.
Excellent service and prices. I was not award of inflight entertainment.
They gave me a seat with extra leg room. But they didn't offer me anything to drink, just because it was an hour flight
I was happy with the flight. It was too short for food and beverage service. (no problem) We left SLO on time and arrived in San Diego on schedule.
Outside Sky cap would be helpful! No entertainment (TV screens)
There was a loud squeaky sound the whole time we were flying.
Had a broken tray in business class. Crew just shrugged it off.
I didn’t like that I could not select my seat and was assigned a seat when I checked in at LAX
Great experience overall. Check in at Austin was congested as they only have about 6 check in kiosks, one was broken, and there was a lot of Spring Break travelers.
Bag drop off was slow and annoying. Only 2 agents at the entire delta desk, and no one directing traffic for what line to be in, many confused people slowed down the process. Boarding was fine. Seats in Delta comfort plus were fine. Snacks were great! Definitely a bonus. The entertainment system was awful — old, slow, not responsive, and completely unable to play games due to some kind of error. But on the other hand, thank you to Delta for the free WiFi. That made it better.
Everything was very good other than I had selected a specific seat when I booked the flight and they changed it once I checked-in the day before my flight. I was still in first class but lost my aisle seat for a window seat. Being tall, the aisle offers more comfort so I always select an aisle seat.
Flight diverted in SD. Later take off in Seattle by 1.3hrs
Crew was not friendly when I went to request a seat change.
Really impressive staff at airport and on plane, especially given how busy it was
Was a great smooth flight from Detroit to San Diego.
they made me check my carryon. There was space in the overhead bins.
The plane was delayed 2 hours. The wifi did not work. The seat in first class was not comfortable because the bottom felt like it lost all of its padding. And I did not like when the flight attendant made me wait at my seat to use the bathroom and didn't tell me why. If there were too many people using the 1st Class bathroom, she should have told me to go in the back, coach bathrooms. I guess I have to feel fortunate that they found 2 local pilots to still fly the plane tonight after the original pilots ended up at an airport 60 miles away due to high winds.
The crew were really great, but the 4 hour delay in small chunks was the worst.
For a 22 minute flight all you expect is for it to be safe and comfortable
Lost connnection had to stayON in Chicago Was a mess
Just a crappy airline. The same every time. You feel you are a cow on a farm. You are being being whipped and pulled.
Wasn’t very crowded. Seamless processes. No issues traveling with two little kids.
My interaction with the flight attendent Eve was horrible. I was seated in 3F and was blown away watching her repeatedly skip me as she took other customer orders for lunch...she took the customer next to me but skipped me, then took everyone's order around me (in front of and behind me) . After she had taken every customer's orders to include those behind me, she came to me and said we are out of everything except one last item. I was mortified, in that, I am a 1k flyer, had pre-ordered AND as an African American could only assume why she repeatedly skipped me...mortified. no words
The Flight was good, pilot seemed very skillful. My wheel chair sister who could barely walk was allotted the second last seat in the aircraft, with great difficulty she managed to reach on her seat, as she required attendance we were given separate seat, even on request no one cared, so much so there were single passengers who were given twin seats. May not be taken as complaint but a reminder to the checkin staff to keep in mind in future the allottment of wheel chair passengers seats.
Almost 2 hour delay in boarding with all standing ready to board at original time. No explanation given.
Overall the flights pretty good. The snacks we’re good and they were plenty of them. Both boarding and deplaning went quickly.
Delayed abs delayed Gate crew giving poor info - we are definitely leaving at —- Ultimately to cancel flight after 4+ hours of delays Just cancel it earlier
The flight was scheduled to depart DCA at 12:30 pm but was delayed twice on the ground so that we were finally scheduled to depart at around 4:00 pm. Once we boarded, it was announced that takeoff would be delayed again to fix a hydraulic problem which delayed our eventual takeoff until around 5:00 pm. Once we departed, it was a smooth flight back to ORD. We did not get any explanation about what caused the original significant delay. In my experience, this happens frequently with AA.
Lots of weather delays that were poorly communicated and managed. I get there are weather delays but they didn’t make it clear what was happening or comfortable on the plane
Everything was on time; the flight attendants and the gate personnel were very pleasant and helpful.
Our second leg to Jackson WY was unable to land due to weather. We were flown back to Dallas after stopping in SLC. We were given hotel rooms and vouchers. We were told that we would be back on the same plane in the morning. Instead we were given a different flight with different seats. Not a good experience. No one knew what was going on.
Perfect flight. On time departure and early arrival. Smooth flight.
Awful! The flight was delayed and we sat on the plane in DCA for an hour because fuel was out in the wrong part of the plane and would not be accessible during flight. So the plane had to be refueled in correct tank. They also allowed someone to get off of the plane. This delayed my six hour flight by an hour and made me miss my connecting flight. I ran to new gate and American Airlines agents new about the delay and even knew that I was trying to make the connection. They knew thru communication with my friend while in flight that I was in the airport and running to the new gate and they still closed the gate and refused to let me on the new flight despite plane still being at the gate. It was horrible and I had to be rebooked on a flight for 24 hours later. This has been a nightmare and if American Airlines can cause customers to be delayed and then have zero empathy as having an on time flight was more important to them than helping a customer who was delayed by no fault of her own, then it's seems that it's not a company that I want to continue to give my loyalty to. I'm so disgusted.
Help was available but timing was bad in my case
It was a horrible snow storm, but updates were inconsistent and the app never displayed a remotely accurate time or gate until very close to boarding.
They cancelled the flight then did nothing to help us rebook. It was awful - I won’t fly with them again
The truck that was refueling the plane drove away with the hose still connected to the plane and ripped part of the plane off with it
The boarding time. I was in Section 1 the lady in charge just let people in section 3 without see us. Make a line , I have to step out and ask her. We were in the line and she just take my ticket and that’s it, so if I don’t ask her she could leave us at the end! We paid more for that privilege and. She doesn’t care….
See my previous comment which is mostly about our flight from Phoenix to SFO
The check in at the airport was awful. Told I need to pay for a bag. The item was taken at screening. I went back to get my $ back and they gave me a coupon with a QR code that doesn’t work. Worst costumer service ever!!!!!
4 hour delay because they used our aircraft to fly a different segment (per the captain)
Lost baggage on my connecting flight. 24 hours later, still no update on my bags.
I had to cancel within 1hour of the reservation an they put you through hell to . no live customer service desk. I'm handy caped and they make it almost impossible to cancel. They are steeling my money. You should not have that airline on your site. Contact me and I will give you all info. Of what the are doing to me just notable treatment they are set up like that to take people
It’s a cheap airline. I wish they had better seats.
Seats are cramped and very uncomfortable. You have to pay for everything and it is too expensive.
