3 hour delay. Had to change plans and was still delayed.
3 hour delay. Had to change plans and was still delayed.
The flight crew was extremely rude and especially not helpful when our flight was delayed.
Ever since Southwest starting charging for bags, passengers don't want to pay to check their bags, so the gate agents have to beg people to check their roller bags now because there's "not enough space". This was a terrible business move by Southwest.
Delays delays delays. Late taking off, late landing, wait for a gate, etc.
First time traveling on Southwest since bag fees were implemented. Usual good service. Just more expensive now.
Our flight to Oakland was great bc the plane was new but it was delayed by 15min not bad at all. Over all it was an 8/10
Flight was on time. Friendly staff and flight was smooth. We Love Southwest.
Internet only worked half the trip Drink was flat Staff was great
As usual was very late. This has become a norm in southwest tobhave every flight very late
I had a great flight from Sacramento to San Diego on 2024-09-20 (at 9:00 am). Everything worked well, the crew was pleasant and efficient. Thank you!
Flight was canceled in good weather due to mechanical issue. Rebooked to flight to different airport in area that landed 7 hours after initially planned arrival. We had to jump through hoops to get taxi reimbursement given flight landed in different airport at 12:45 am.
They cancelled the 6am flight around 12:30 AM the day before. I was luckily able to book through another airline. I called for a one way fare refund, the new flight is much more expensive. I lost $$$ in the difference and this caused lots of stress. I intend to take action following my trip, really off to a bad start and I will never fly Alaskan again
My travel mate needed wheel chair assistance getting on and off, and it was excellent. Thank you!
Over all it was great. My original flight was canceled but they quickly rebooked me. I was frustrated because I had to cancel my entire plans for the day but all considered, not bad. The crew tried to keep us calm while we sat in the plane for was felt was an hour or so but they could use a bit of a script. The seats were comfortable and I would give it another try.
Not able to get boarding pass for domestic connection flight when check in at international airport. I was told I need to get connection flight boarding pass after I entered US. It us very inconvenient.
The gate agents begged us to check our carryons. They BEGGED us, over and over, and said that the flight was completely, totally full, and said that if we don't check our bags, it will cause huge delays. They finally said that "group suchandsuch will be required to check bags!" So I checked mine. Well, the flight wasn't close to being full, and many of the overhead compartments were *empty*! Moreover, my bag was delayed at the carousel, and it wasn't on the carousel that was posted. COME ON, AIRLINE, you can look at the seating for the flight on your computer and decide whether it's really necessary to beg and beg and beg people to go through the hassle of checking their bags! This is annoying as hell and makes me not want to use your crummy airline ever again.
It is a hassle to not have entertainment screens on the backs of the seats.
No headphones provided. No gf food. Only 1 beverage cart run sAN to HNL. Rarely saw crew members
A solidly good experience, but would’ve appreciated more communication with regards to travel delays.
No issues and clear sailing. What a preferred to have sat in one of empty seats other than my assigned seat that would be my only complaint if it was to complain.
It was a short, comfortable flight. It did leave an hour late due to the pilot having to be replaced (family emergency) but that didn’t inconvenience myself & my friend. The situation was explained, eventually.
UA594 was delayed multiple times. I ended up getting picked up so I can make it in time for work 6AM on Monday, 7/6/2026
Service was professional and quick. Premium economy seat was comfortable given the class
The staff was extremely helpful and friendly at all times! They went above and beyond to get us into an earlier flight in San Diego to make our connection in SFO possible, because our original flight did actually not make it! I did so much appreciate the UA team and how they made this possible. We also didn’t have seats together on the long flight to Singapore, but they found us seats together last moment with no additional cost! Nobody sat next to us, so that we were able to sleep! Thanks to UA for improving their service and Underpricer for booking this trip! Please be careful: 1,5 hrs for transfer in San Francisco might not be enough time in the future
Horrific. They missed my connecting flight to San Diego. I didn’t get there until Monday at 9am when I had a mandatory court settlement conference scheduled at 6am since we had parties on the east coast. This caused many issues. All because United apparently forgot to hold the doors open until my flight landed that only had a 10 minute delay. This was the last flight to Southern California. So I couldn’t even rent a car to finish the trip. United cannot be trusted when traveling on specific days and times since weather didn’t have anything to do with the delays.
Was a pain having to leave the plane and reboard but glad the plane was fixed
Connecting flights were poor,especially in Naples.our Lufthansa air bus was a joke.way too small for that long of a flight.no room at all.couldn’t even get out of the seats to move around or go to the bathrooms.we thought we were getting an actual air bus,double decker.i will never fly that long in a plane like that again.kind of misleading to call it an air bus.we actually had more room on our buses that we used.
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
Booked economy through United - air canada treated it as standby and was almost refused boarding.
Terrible. The canceled my entire flight when I requested a refund for a trip frontier canceled trip one way.
i was unable to check in the flight. refund requested
Great for the price. No wifi or entertainment, but gate agents and crew were fantastic and we boarded quickly and left on time.
Decent clean onboard experience. Okay discount airline experience. Unfortunately, any customer service interactions are difficult and unhelpful. There is no service. Also, a premium seat only gets you premium boarding if you line up first. Once they start general boarding you must go to the back of the line. Not very premium
I went to the Frontier counter in San Jose at 1030am or so on Sunday 10/13/24 to see if I could get an earlier flight to San Diego in lieu of my reserved 630pm flight. One thing led to another, and I was able to obtain an open seat for about $ 56. on the earlier flight. Fine. Then the agent asked if I "was checking a bag". Not knowing that carry-ons cost extra per Frontier policy, I thought that she meant a regular checked bag. Therefore, I said no. Once I got to the gate, the same gate agent who sold me a ticket told me that I had to pay $99 for a carry-on, and that all bags were extra on Frontier. Having never flown on Frontier, I was not aware of this. Part of the issue was that she was not a native English speaker, so there was a miscommunication as to what "bag" meant. I would have preferred for her to have clearly let me know at the front counter that any bag including a carry-on cost $99. It would have had the same outcome, as I had to take my carry-on. But it got hectic at the last minute at the gate itself. The baggage policy should have mentioned "including carry-ons" when we first spoke.
Literally everything could have been better. Why are the planes always late?
9hrs delay and didn’t provided anything until after flight landed $75 voucher for fiuture travel no meals or anything.
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….
