Great experience flying Southwest. The crew was really kind and helpful, and very friendly with our toddler.
Great experience flying Southwest. The crew was really kind and helpful, and very friendly with our toddler.
Very good. Sad to learn Southwest is going start to charge for bags
Our flight was diverted from being a non-stop to getting within 150 miles and requiring another plane. We heard 4 or 5 different versions from SW as to why we had to stop, then wait for a replacement plane. Five hour delay, weather did not come up as a single excuse.... communication was not clear and well explained. No one really took charge!
My flight to Chicago left and landed early. My return flight left two minutes late and arrived 2 minutes late. My seat selections were ideal! There were no snacks going to Chicago and no snacks on the return trip. There are no charging outlets on board.
WiFi on the flight was not working. Thus, entertainment options were limited.
Great flight staff. Ease of boarding. Overall, very uneventful and easy trip.
Plane late from DC to Austin 30 minutes. Crew made up much of the time enroute to San Diego.
Gate agents were informative and friendly… flight attendants were as well. Had a fun time chatting about their legacy AirTran experiences as a former fan of the airline that Southwest acquired.
Flight was awfully bumpy and landing was a bit jolting. I was in the restroom when snacks and drinks were served and was not asked if i wanted any. I had to ask for water finally.
Wi Fi was horrible kept cutting out the whole time and too expensive
Flying in both directions across country the gate designated on my boarding pass was wrong. From w to e across the country the passenger next to me coughed the entire way.
Although both planes (flights) had mechanical issue delaying both of my flights, the crew members handled everything with ease. Both flights had the smoothest take off and landing. I opted to upgrade my seat to first class and really lucked out getting the seat at the very front of the plane. Awesome treat to myself. I really enjoyed my flight.
The staff from check-in counter to the flight crew were great. Flight was right on schedule. 10/10
Changed flight from San Fran to Seattle Then with a Delayed takeoff barely made my connection Waited over an hour for luggage 😜
It was good. There was a mistake made in Seattle. Somehow we were bumped out of our seats as if we weren't on the flight anymore. The woman at the gate caught it and announced our name to come up and she fixed it.
I wouldn’t fly with Alaska again if you paid me.
Our flight experience started at the check in kiosk. Jennifer Polete smf 498304 greeted us and assisted us with our tags and check in guidance. She was so pleasant, helpful and friendly. This was the start of my experience with American Airlines and it made such a wonderful impression. The staff on the airplane were also kind, courteous, and attentive. I would definitely fly American Airlines again
I appreciated Alaska Airlines very much, they are expanding traveling locations globally as they partnered with another company and am excited and looking forward to our next traveling adventure with this great Airline. Thank you kindly
Food and entertainment were inferior to jet blue The pretzels were way too garlicky
Pretzels are awful. Empty calories. There’s gotta be something else.
Flights on time. .Ride was as comfortable as can be expected in steerage. Luggage arrived at destination. Attendants were fairly friendly.
Great staff. Wifi is terrible. Signing up for skylines is a painstaking process. Had to call customer service just to get my flight itinerary and confirmation sent to me. Consistent delays. A well staffed company that is run so poorly. Upper management needs to be renewed.
The WiFi didn't seem as fast as it normally is
Thank you for not flipping the plane on the run way. You guys get a 5 star rating for the flight!!!
The crew was wonderful and attentive. The seats near exit row were restrictive. Offer healthy snacks please
Delta is a premier airline so my expectations are most always met.
Seats are much much more comfortable than United, which is what I usually fly
Zero updates from the pilots for 30 minutes in the tarmac
Boarding is, as it always is… horrible. Gate lice. Slow moving zones. Too many people with carry ons
I loved having a most black flight crew during Black History Month; rather by design or accident I appreciated the representation. ❤️
The seats were crammed and the guy in front of me wouldn't stop reclining. If AA is cramming extra rows in, they need to take away the reclining in coach. My knees were smashed for 4 1/2 hours and I was very close to confronting the passenger in front of me.
What, first class and not even a cup of coffee before landing at 5 am in First Class? Really?
I paid for what I got which was cheap, I brought my own entertainment. I knew what to expect, so I could be prepared. If you’re flying economy, check in early like me. I have no problems with my flight, was on time, staff were friendly, and overall good experience.
Customer service in first class does not exist on American Airlines
Flight was delayed due to a steering issue with plane. The delay caused me to miss the connecting flight. The delay caused me to spend an extra 21 hours in airports and flights to get to my destination. The plane issue obviously should have been found and fixed before we even boarded. Ridiculous.
Had to go get beer myself from attendants in the back of the aircraft
My flight back my reservations were list because they said I didn't pay my pet fee when I had a receipt
It was exactly what I expected, actually arriving sooner than scheduled.
Delay 14 hours! Missed all connections and had to fly different airline the next day.
Excellent. Attendants served preflight drinks and were courteous and nice.
I was not permitted on my flight and had to purchase another flight ticket to Las Vegas.
This was a full flight and I was in Zone 1, however upon boarding, several other zones went in ahead of me, leaving no overhead cabin space near my seat. This created a challenging disembarkment process.
Frontier had yet another flight cancellation. Have never made a complete round trip with this airline without at least one leg getting cancelled. Miserable flights - dirty, uncomfortable planes that apparently always have issues since I've had multiple delays and cancellations with them.
Flight was delayed 3 times, would have been nice to have received text message instead of email notifications. Frontier app wasn’t even updated accordingly, no gate number disclosed. No agent at front desk of gate to inform of delay. Very confused and left if the dark
It was a no frills flight. Would have liked to be able to charge my device
The flight itself was ok and the pilot was very communicative. However, our flight was delayed for almost 3 hours, the gate was changed 3 times and there was no communication as we were waiting. The flight staff was overall a little crabby...I understand as they probably had a long day but we all did.
Asked for a seat change to be w my wife at the gate they were great in sorting it out to make it happen
Everything went as planned. Crew was great. Seats were still not that comfortable.
The plane failed preflight inspection, so we sat there for 90 mins while they tried to fix it. Ultimately, everything was remedied and we made our connecting flight; instead of a 2 hour layover at the airport, we spent it waiting on the plane.
They changed the timing , first delayed by 4 hours then went back to 40 mins late, we had to run back to airport to not miss our flight. This is ridiculous
