Pros: "Quick boarding"
Cons: "With flying there is nothing perfect all the time. I was able to sleep on the flight and had a place for my carry-on luggage. I wish unboarding was mad less complicated."

Pros: "Quick boarding"
Cons: "With flying there is nothing perfect all the time. I was able to sleep on the flight and had a place for my carry-on luggage. I wish unboarding was mad less complicated."
Cons: "Less announcements about masks we get it We don’t need instructions on hand washing Drink service needed"
Cons: "This plane was too full for social distancing. I was really skeptical about this flight as it relates to the COVID pandemic."
Pros: "Competent crew"
Cons: "Too many people, especially children running up and down aisles during flight. Not adhering to COVID guidance. None of the crew addressed this ☹️"
Pros: "The crew was good, and the airline tried to make our wait in the airport as comfortable as possible."
Cons: "The four-hour delay was really hard. Since it was in DC, I don't know why it took so long to get another plane."
Cons: "Communicating take off time!!! It changed multiple times by one three hours and ended up flying the next day!"
Pros: "Just the crew was super sweet and amazing. Everything else sucks. My seat won't recline and the flights get delayed all the time. Worst was the state LaGuardia is in right now."
Cons: "More on time performance would be great from Delta. Seats that actually recline and not get stuck. Screens in all the seats to enjoy entertainment."
Pros: "The flight crew was friendly and communicated well. They also had a friendly attitude."
Cons: "A 1 hour wait for wheelchair assistance in Houston and then a 30 minute delay for wheelchair people to take my mom to baggage claim. Then the wheelchair attendant kept complaining she wouldn't receive a good tip to take us to the Lyft pickup area."
Pros: "Information communicated about delays."
Cons: "- more communication (any!) about bag status when landed - flight delay due to too many/too heavy baggage. Long delay was said to be due to making sure our baggage would accompany destination. Upon arrival, bag was left in NYC but this wasn't communicated. No info on bag status at airport or via ema"
Cons: "First class seats were too close together. It was very difficult to get out of you seat into the aisle. Food was not what it should have been for 1st class There was no wall between 1st class and coach giving little privacy when I worked my laptop. it was in direct view of the middle seat in coach"
Cons: "The AC was off while we were waiting to takeoff so it never felt cool in the cabin for the hour(ish) long flight we had. I don’t know if it was the size of plane that made it so we couldn’t have that on while taxiing/waiting our turn to take off or what, but it was too hot and stuffy onboard in Texas on the tarmac. Our next flight from Dallas to Huntsville, AL had the AC on the entire time we were waiting our turn/taking off- the plane was newer and slightly bigger. Not sure what the deal was but it made the flight pretty miserable."
Cons: "If American Airlines didn’t delay 10 minutes so you miss your connecting flight twice within 1 trip"
Pros: "Very friendly crew, my flights were on time, good selection of movies. That's about it."
Cons: "Their Basic fare should be renamed "Bare-sic" – you have to pay for almost anything. Food choices can be better. I guess they can pay the Munich airport to get better treatment and not having to bus their passengers around."
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: "The communication on the actual flight could have been better. The flight from Houston to Charlotte was not very informative as in weather conditions, traffic, or the time in which we landed was not gone over."
Cons: "Smoke in cabin, has to return to Houston. Then they never transferred our luggage as promised."
Pros: "Much better the typical American cattle class. Qantas actually served real food. Cabin was spacious."
Cons: "Crew was very rude and the inflight food and entertainment was horrible. Food wasn’t edible and my tv didn’t work"
Pros: "Easy boarding, smooth takeoff"
Cons: "The loud child behind me kicking my seat and yelling"
Pros: "Very little"
Cons: "Gotta fly from HOU to DFW to get anywhere ... Delays, running from gate to gate .. meanwhile AA staff and gate agents are always scowling and never helpful. In general, flying is expensive and sucks."
Pros: "Stuartess provides free first class items like blankets and drinks."
Cons: "Social distancing was not practiced by using nearly 50 middle class seats left empty while the entire rear of the plane was jam packed in economy seating."
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."
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: "Everything was fine and normal except the crew."
Cons: "My flight was a later one in the evening but all the crew showed was that they were ready to go home."
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 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."
Cons: "Another passenger was extremely rude to me. Causing me to have to move seats mid flight. Crew did not try to resolve the issue with the man behind me and put me in a worse seat. Horrible."
Cons: "I was unable to go on the flight because of the extraordinarily high cost of changing a last name from a maiden name to a married name. I was so disappointed by the service."
Cons: "The food options are poor at best and it's really sad that they don't offer anything for free. My ticket wasn't cheap so I can't imagine they're saving me money on my ticket by not offering better food on that long of a flight."
