Airline reviews
Pros: "I almost got a chance to sleep."
Cons: "One of the people with a crying baby in the seat behind me decided to sit in the seat next to me. I just wanted to sleep. It was a miserable experience for me."
Pros: "I almost got a chance to sleep."
Cons: "One of the people with a crying baby in the seat behind me decided to sit in the seat next to me. I just wanted to sleep. It was a miserable experience for me."
Cons: "The WiFi was spotty, which made the Peach Bowl game difficult to watch, but overall it was great."
Cons: "The shade on the window was broken so I couldn't closer it."
Pros: "Flight was on time and arrived early. Crew knew what to do and made the flight run as smoothly as possible."
Cons: "Courteous service is there. I do not think of anything better."
Pros: "Southwest crews are always amazing."
Cons: "We were delayed about an hour, but since this is the first delay we have ever experienced on SWA, we think that's pretty good (and probably really lucky too). The only thing that bothers us on flights is that we wish you would enforce the carry-on size rules."
Cons: "Help customers look up and find the best alternative routes when things go wrong with delays and cancellations. I've been through enough only to have to egg an agent on to help me."
Pros: "Affordability was the strongest motivator in choosing Southwest."
Cons: "I hate that you have to pay extra for the opportunity to sit together with fellow travelers."
Cons: "There was no wifi on this flight. Make sure to bring your headphones and backup music."
Pros: "The crew was very awesome and pleasant"
Cons: "non-assigned seating is horrible (business trip, I didn't get to choose). The seats were more narrow than I've been on before. I ended up getting a middle seat and even with my arms pulled in front of me and my legs pushed together I was constantly touching the other passengers. I'm 5'10, 230lbs"
Pros: "Crew was very pleasant. Boarding and deplaning was smooth and easy!"
Pros: "Availability of WiFi, a charging port and media options puts Delta a step (or two) ahead of their competitors. The professionalism of the crew, as well as the complimentary food/beverage options are also excellent."
Cons: "Not the airlines fault, but my 6’4” frame doesn’t fit very well in a middle main cabin seat."
Pros: "We arrived eventually."
Cons: "Flight delayed three hours. Payed extra for an earlier flight. Very disappointing."
Pros: "Crew."
Cons: "Getting to Venice on time. Our late arrival cost me a 90 euro shutle."
Cons: "Have rhe right to carry at least one luggage per person at no cost. Besides carry on and personal item. Tickets prices and luggage costs are extremely expensive."
Cons: "Denver airport is far too large for there to be such a small security check therefore it took forever and I missed the flight. Delta tried to charge me $1000 for another ticket to Albany and I decided to fly with another airline for half the price instead"
Pros: "The service is very good from the beginning. The flight attendant is very caring thanks so much."
Cons: "The seats were in bad condition, I was surprised as Delta usually has well cared for interior and exterior airplanes."
Pros: "The flight attendants were all helpful and pleasant. The seats were comfortable. We were provided with plenty of liquids."
Cons: "The landing was pretty tough and we took off almost a half hour late."
Cons: "Flight cancelled due to weather that was never bad but on the potential of bad weather. Had to scramble so my 18 year old son was not stranded overnight in a strange place and Delta does not help. Only rebooked a flight itinerary for the next day for a 4 hour flight with connections on a 1 hour direct flight. Spent an hour on line to figure out what to do. #neverdelta"
Cons: "Paid for First Class so I could sleep on this red-eye. Wasted my money. Seat was uncomfortable, legroom in my bulkhead seat was horrible. I can sleep anywhere...make that ALMOST anywhere, now."
Cons: "I never made it... I had a trip interruption and got stuck in Chicago and would of had to wait another full 24hrs to take the flight to Denver. tired and nauseated after being all day at the airport that at midnight, i knew that I couldn't hold off till the next evening, took the next flight back."
Cons: "The flight was delayed which caused us to miss our flight in London our family was delayed for 12 hours"
Pros: "The crew is good and attention"
Cons: "They need to prevent to inconvenience or un conformity towards to the people or customers becouse they don't give information in time"
Cons: "Delay due to equipment failure, were not able to estimate delay"
Pros: "Older style cabin, but still a comfortable flight. Crew was friendly."
Pros: "Food was good. Staff was polite."
Cons: "Both flights were late leaving. Plus then we waited on board for a long time. Once on board and waiting, no explanation, no updates. No idea what was going on or why. An announcement would have helped a lot. Philky-Prg: Long delays with food , staff was slow on the Philly -Prg flight. Seemed like they didn't want to be there. No info from flight crew. Phily to Prg - Crappy old plane that should not be flying over seas anymore. Applies to both flights unless specified."
Pros: "seat"
Cons: "Staff seemed exhausted. American has no customer service phone to explain to customers what is going on. Bad experience all together."
Pros: "Crew was nice and friendly. Pilots flew great. We arrived a few mins early as well."
Cons: "On the way to Denver from Miami we were on a nice new AA plane with TV entertainment, movies, power, and comfortable seats. On the way from Denver to Miami we were on an old plane with no entertainment and old uncomfortable seats. If this is going to be the case, charge me less up front as well. My daughter had a terrible time for a 4 hour flight."
Pros: "Seats were comfortable enough"
Cons: "They force you to get to the airport really early."
Flight was delayed. Connecting flight left 5 people - pulled away from the gate 10 min early with no connection options until the next day !!!
Cons: "Kept us on plane for 90 mins while changed a fuel filter. This got us home at 230am."
Pros: "We arrived nearly on time & without issue."
Cons: "The plane was warm & no cool air was being dispersed in the cabin & because of that it was very dry. Better temperature regulation, climate control is needed to make fir a more comfortable flight."
Cons: "Offered a snack. The airplane magazine mentioned them, (for a cost) but they weren’t offered for sale."
Pros: "The crew was great and the landing into Denver was very smooth."
Pros: "I like flying Lufthansa for entire trip then changing to united airlines"
Cons: "Particular everything the airline"
Cons: "I missed having the navigation map when traveling such a long distance."
Pros: "Flight was on time. Friendly crew."
Cons: "It turned out that we were on stand by (without anyone telling us until the morning of the flight) and did not know if we were going to fly out. We could not select any seats at check in and only found out our seats a few hours before the flight. It was quite unpleasant and stressful as my husband and I were flying with our two children and faced a real possibility of not being able to sit together or getting bumped off a flight all together. It was a code shared flight between Lufthansa and United and each airline kept sending us to the other to get any answers or help. neither were helpful. It made it for an extremely frustrating experience."
Pros: "The app promoted me to check in on my phone and would not allow me to check in. So I assumed the time on the ticket would be my boarding time. I was late for my flight."
Pros: "The boarding and seating happened in a timely fashion, and the crew was courteous. The lunch meal (I had requested Asian vegetarian) wasn't amazing, but not as bad as it could've been."
Cons: "The flight was not with Lufthansa, but it was actually through United, which was extremely confusing as I did my ticket confirmation, seat booking and meal choice through Lufthansa prior to my trip. To find out on the day of the flight that I had to check in and go through United was extremely annoying, as the counters are in different terminals and it was unnecessarily stressful. The flight itself was crammed, with absolutely no leg space, and not even enough space under the seat to stow my backpack (which had fit perfectly on my Brussels Airlines flight to Madrid). I had requested the Asian vegetarian meal, and the snack we got prior to landing was pretty much two slices of cucumber on a small bun (and an apple on the side) - extremely dry and hard to eat. I asked for mayo, but the flight neither had that, nor any other condiments to make the "sandwich" more edible."
