Appreciate efficiency and early arrivals. Missed video on such a long flight (DCA to SFO).
Appreciate efficiency and early arrivals. Missed video on such a long flight (DCA to SFO).
I paid $49 to select my seat---6A a window seat just behind first class. When I started to get on the plane I was told that my seat had been given to someone else and I now had a middle seat. They finally gave me an aisle seat. When I told them I wanted my $49 back, I was told I would need to call alaska and fight with them to get my money back. And when i was on the flight people going by kept hitting me with their bags. I have tried calling alaska twice to talk about a refund but never got thru to the right person!
All 4 members of my family found the seats terribly uncomfortable. 2 of us suffered from back issues the next few days.
Delays, delays, delays.... (and) Told no room for carry on after boarding B Group and told to drop off our carry on at door to be checked in instead. There was plenty of room left in the overheads above our seats right up to the end of boarding!!!!
Like I said before the internet was shut off so there was little to do on this leg of the flight.
Nice, competent people and airline. Did the same flight last year and it is a pleasure. Only part of the experience that could be improved is the JFK terminal. Hopefully that one is part of the renovation.
Our flight was diverted to Spokane, WA bc our crew timed out. Then we were flown to San Francisco
Your staff said the call button is for emergencies only now? Unreal. Also every one who welcomed me aboard was staring at their phone. Why even bother..
I was able to upgrade to first class, which was great. Food and drinks were underwhelming compared to other first class flights I have taken.
Cross country flight ... there was no entertainment system... for any flight over 4 hours there should be some entertainment. There were 2 drink and cookie services only (which is ok, but not special)
It was terrible, if they ran flights on time it would make a big difference.
Delta seems to be improving in many areas, except they are super bad with the food available. Bring back normal food service on long flights.
If I pay extra for "comfort+" I expect leg room where I can stretch my legs. I was seated with an attendant's seat blocking my feet. Knee space was fine but my feet had less room than the non-"comfort+" seats. Also, don't go cheap on food when you have flights of 3+ hours. It's insulting.
Only one side of the heafphone jack work. Crew was friendly and helpful.
Great. Flight departed early and arrived early. Deplaning and baggage claim ww were quick.
I actually received a notification from kayak on email but not one by text from Delta when my departure gait changed and I almost missed my flight
They separated our seats and moved us to the back of the plane. Hundreds of dollars and thousands of miles used and this was my platinum member experience.
AC barely worked on a 50 minute flight. It was very warm the whole flight. Flight was very bumpy and hard landing.
Got on the plane and then needed to deboard the plane because they didn’t have any pilots?
The flight was canceled two hours before departure, it took over five hours to rebook us on another flight.
For the most part united was a good experience, how ever when they came by with the snacks and water, they completely passed by my wife and I. As we were in separate rows. On a 5 hr flight we were not offered water
Fantastic crew. Flight was delayed at last minute but we were given updates every 20 minutes and the crew was so friendly and considerate. I miss the touch screens on the back of the seats, wish they would bring that back though.
Awful. Worst airline I have ever been on. Crew were among the rudest people I have ever dealt with. United staff members were rude and disrespectful. My flight was delayed, causing me to miss a connecting flight. I understand things happen, but when staff start lying about what actually happened, that is when I have an issue. Just be honest, really it isn’t that hard. I’m being very honest with this review and I don’t find this difficult what so ever. In fact, because of United Airlines, my Christmas holiday was off to a really rocky start. As someone who has traveled across the world, it has only been United that I have had a truly awful experience.
Good flight. On time. Boarding and seating was easy. Crew were really friendly, yet professional. Bathroom (by cockpit) was small but serviceable. Some the seats were showing some notable wear & tear, but were comfy. Very happy UA customer. TY! 🤛🏽💗
We were delayed 3x and because I didn’t purchase my tickets directly from United Airlines I was told I Have to take care of it myself so I called Underpricer and they helped me but before I changed my flights I took the risk of sticking by what my tickets were and was lucky to have gotten on the original all flight with only 15 mins before take off. not sure if I will do this again
Everything good until we waited for jet bridge at SFO. Then pilot gets on speaker & said it won’t reach plane- too short, need to go to different gate. Then 5 min later, adjusted plane/jetbridge & all ok?!?
We had to wait almost an hour for the wheelchair porter to be ready to pick up my mother. And when she arrived in Newark airport the porter was not there and she started walking with her cane and her poor mobility. When the Newark porter found her they didn't want to transfer her bags to the wheelchair for her.
Great onboard crew. Boarding was a zoo, I got in line before pre boarding in Group 2, still had my bag force checked. WiFi was glitchy all flight. Seat and bathroom are both tiny unless you pay $$$ for first class.
Cabin was pitch black, even during meal service. The reading lights for seat 2E/F did not work, and seat 2E did not recline.
Was realllly smooth. It was delayed but we were well informed.
DO NOT BOOK THROUGH AMERICAN AIRLINES IF YOU HAVE ANY ADDITIONAL NEEDS. Great flight, crew etc. it wasn’t full so had space to stretch out Only downside was there was no GF option for my partner. We booked through American and it was a Qantas flight so despite contacting both airlines to confirm, she didn’t have a gluten free meal for the 16 hour flight (nor the flight in the other direction). The flight attendants did their best to accommodate but it was not super substantial.
We boarded after several delays due to mechanical failure and a gate change. The seat cushion in the exit row was very compressed and offered no cushion, making the four-hour journey reasonably uncomfortable. The WiFi worked for a few people, but for most, it did not, and you cannot get entertainment unless you can connect—American Airlines flights do not have seatback screens, and you must use your mobile phone.
It was as expected for such a short flight. No complaints
Crazy seating issues. We got seated far apart. Offered middle seats at a premium rate. Why is a middle seat now the expensive seat? Baffling.
The boarding process was a nightmare and though we were traveling business class, we were in Group 2 and the organization was terrible. The Business Class on this flight was crowded and did not feel clean and nice. Overall, I would not travel Business again on the American Airline flight through British Airways Not nearly special enough for the considerable cost .
The boarding process was such a chaos with everyone crowding at the gates. There was no structure. The onboard crew were fantastic and very good.
For coast to coast travel the A321 and even the NEO, even in first class will never be excellent. That would take a B787 or 777 to accomplish.
Seats were very uncomfortable. I paid extra for a seat with more leg room, the seat was no different than a seat at the back of the plane. Flight attendant was rude.
I did not enjoy continuously being lied to about the amount of time we would circle Chicago before deciding to redirect to Milwaukee. Then the amount of time we would sit on the ground in Milwaukee waiting for gas, or to take off again. Or the amount of time it would then take to get to Chicago again, or sit on the runway waiting for a gate. The whole time continuously hopefully we would make our connecting flight that kept getting delayed as well. Only to scramble and miss it. Enough with the BS. Tell me the truth. "Sorry, things are backed up and your probably not going to make your flight. You should rebook on the next flight now rather than wait." You'll never hear those words from an airline. Speaking of which. If the flight has been redirected and/or is seriously delayed, how about making the WiFi free for everyone so they get to rebooking and reserving hotel rooms while still in the air. You've inconvenienced me already and now you want me to pay $20 for Internet so I can try to make other plans. Absolutely disgusting!
not enough crew for business class and not great service as a result. underwhelmed overall
I loked walking out on the tarmac to board and no first class. I didn't like that they have no snacks or onboard wifi to bide your time.
The plane was clean, the crew was friendly and helpful. It’s a low cost airline so there was no food, drinks or in flight entertainment but we didn’t expect any of these things. In the room for improvement department, they should install USB ports in seats to charge mobile devices.
I was surprised that all baggage, including carry on, were charged. Each additional bag went up in cost. Really disappointed in the additional costs.
It was a redeye flight, so every passenger just wanted to sleep, but through the entire flight, the flight crew made announcements over the loudspeaker at maximum volume every few minutes making sleep impossible. For example: it’s 2am, and the crew decides to give an extremely detailed announcement about snacks and beverages for sale. And 3am is the perfect time to wake up everyone with a lengthy announcement about how to get a coffee refill and how to take advantage of new offer from frontier for a credit card.
The takeoff was the smoothest I've ever experienced on any airline and this is the first time I've flown on frontier so this was an extremely pleasant surprise!
A lady asked to stop the flight after the tunnel pulled away and we began to depart a flight that was already hours late. The attendance respectfully stopped the the plane and had the tunnel return. After the tunnel returned the passenger claimed to have changed her mind . The tunnel was then put in reverse and the passenger remained on the plane .. They should have sent the sick passenger off the plane like initially replaced. They existed a couple off the plane prior to that situation.. So.. all and all.. it was a long and flight.. .
With frontier you get what you pay for. The flight was two hours late. It’s a tight fit for the number of people they bring but you get to where you’re going cheap. Sometimes that’s more important than a nifty drink and cool TV..
Charges unexpected. For seat that didnt recline. Please reverse extra seat and carryon charge. Bad business that is a bait and switch.
We had an awful experience getting our bags checked in. Frontier’s check in on the app manipulated us into buying the business package because that was the only option available for a checked bag which included two checked bags per person which we did not need. Upon arriving to the airport, we stood in line for what seemed like forever at the baggage check in and there was no one available at the counter. We were first in line and we were afraid we were going to miss our flight due to the baggage attendant being late. After realizing there were a lot of other people waiting at the baggage check in and no one available. I reached out to Frontier and could not get any customer service so I had to call the airport to page the baggage attendant to send someone to the counter to check in our bags before we were able to go through security , I finally spoke to the attendant at the counter and explained to her that we had to pay for two checked bags person a total of six bags when we only had a total of three bags between three people she said to reach out to Frontier and they would issue a refund for the three bags that we paid for and did not need. I reached out to Frontier which I was not able to reach anybody by phone so I had to go through their automated chat feature, which sent me around in circles until I finally reached a representative to assist me. I explained to them what happened and they explained that they were not able to assist me. I continued to push the issue with them as this was very frustrating and they finally put in a customer service ticket where we were issued a flight credit and we were so disappointed because after this experience, we NEVER want to fly Frontier again, and we do not want a credit that we will not use. Frontier charged us almost $500 for us to check three bags which is absolutely absurd! The customer service agents were not able to offer anything else other than a flight credit and I do not feel like my frustrations were truly heard , we will never use Frontier Airlines again ! Truly Theft by Manipulation! They should be ashamed!
I couldn’t check in because the app didn’t work. It took 3 Frontier employees at the counter to get me checked in. Flight left 3 hours after departure time
