SW can't get their wifi right. I upgrade to insure wifi service but the last two trips had intermittent service. Not worth the extra costs.

SW can't get their wifi right. I upgrade to insure wifi service but the last two trips had intermittent service. Not worth the extra costs.

I elected to pay for the upgrades and found very little difference

Flight was hours late, unable to sit next to spouse, I have had so much better experiences. Substantially better, only saving grace was that it was a short flight.

An entire day of delays. Cost lots of money. Meals and a hotel.

Departure was delayed more than 1/2 hour while we waited for luggage (only) transfer from another flight/plane. Once approved for takeoff, the flight was excellent.

Easy to book and to get check in and get on and off.

Everything worked well. Crew was as entertaining as is possible on a plane flight. Southwest still has good legroom:

The crew and everyone on board was wonderful, We had to wait for a flight attendant to come from Orlando to Jax after a sudden illness., We left an hour late and “missed “ our connection.flight. The plane was held for us but we were told that our bags probably wouldn’t make the flight even though we would and would have to return to the airport in Boston pick up our late luggage or choose to fly on the same flight as our luggage. We chose to wait 4 hours on the next flight with our luggage and missed our first day in Boston for our grand daughter’s 10th bday celebration. When we arrived on the next flight, our luggage was sitting in a room waiting on us - evidently it did make out original flight., We were given meal vouchers in Baltimore for our delay which we really appreciated and thought was a very kind gesture by Southwest - sudden illnesses are not their fault., I just feel like we would not have missed an entire day in Boston if you offered more early morning direct flights and /or had offered to deliver our luggage to the hotel instead of us having to return to the airport to retrieve our luggage on the next flight due to a technicality - it wasn't “lost luggage”. Other than that , it was a perfect flight .

It was good. I wish you had gluten free snacks for my husband.

Always dependable. No surprises. That’s how I like to fly!

Long story short, it was one of the better flight experiences I've had in some time when compared with other airlines.

Aside from a completely packed plane, I really have no complaints.

The flight was very good and the staff was very friendly and helpful!

We landed and sat on the tarmac for 45 minutes because they only have one gate at the airport and there was another plane running late so we had to wait

The food is terrible. The staff is wonderful. Comfort is good.

Lounge in Lagos is terrible, food on board from Lagos to Atlanta was horrible. Only bright spot the cabin crew were awesome.

Excellent check-in. Crew was good. Excellent communication from flight deck.

Amazing flight! I have never noticed the uniforms of the attendants before in twenty years of flying except today when one female had the most amazing dress on. It was beautifully designed and showed she was in charge. I never dreamed I would google who designed Delta uniforms . The ultimate compliment is when another woman admires your outfit. . I hope your designer puts it on the market

Our flight was delayed in Atlanta. The staff could have gave us an explanation for the delay and how long it would be.

Flight was on time, the staff was personable & professional, & the plane arrived on time.

The flight had a delay but I made it to my connection. Flight was smooth overall

Everything was on time and service on the flight was great!

This is for UA2274 from Houston to Sacramento. The flight was delayed arriving due to mechanical issues so we left about 3 hours later than scheduled. When boarding the plane the temperature inside was excessive - likely close to 100. Pilot apologized and said it was going to improve at altitude, which it did. But before that I honestly thought there might have been more delays removing passengers made ill from the heat. We were delayed leaving due to another mechanical issue. There was not water on the plane due to a panel that was not secured. They did that quickly, but the combination of mechanical issues was rather disturbing and did not reflect well on United.

No access to the Wi-Fi, noisy group of people made it difficult for me to hear through my earbuds. Snacks and drinks - limited service when your seat is at the back of the plane - people up front are always served first and the back gets whatever is left. Not pleased.

Didn't make it dir to delays - no support from United staff

Flight was delayed in the gate by 5 hours and ultimately cancelled- rebooking service by United agents was terrible

My seat was broken. WiFi didn’t work. Gate crew at HOU were rude and condescending. Treated all the passengers badly. Bad experience, United.

United domestic flight was better than international flight. There was no switch to control Ac In international united flight. Food was also average, Air canada food was much better than united.

They cancelled our flight at the last minute due to mechanical issues. Rather, they “delayed” it till the next morning. A pain in the neck when traveling with two young children. Crew was really nice, which made up for it somewhat. This is the second flight from delta that was cancelled this year. Definitely going to fly another airline when possible

Noticing spectacular about the flight. It got me fro m point a to b. High priced

The gate experience at LAX was abysmal (same for the arrival experience two days prior). Despite the LAX -> SAT schedule of two flights daily, our departure gate was at a smaller hub that we had to be bussed to from Terminal 4. Fortunately, I arrived at LAX extra early and had time to spare, but if I had not known, I might have missed my flight. I looked at the LAX airport map in the AA app and there was no indication of the additional boarding process. Lastly the gate area we were bussed to was crowded with limited food and beverage options. On flight, the fight attendant was hospitable and attentive, the flight was smooth, and AA's free (and working) wifi for AA members were all on the positive side.

It was what i expected. I like the movies you can access from your phone. It would be nice if there was a gluten free snack offered. But I did bring my own snack knowing there would not be a gluten free option

Got home at 3am after deboarding the plane. No compensation offered by American

Awful. Original flight was delayed 5 hours. Had to to take a connecting flight instead of direct. Had a 4 hour layover. I missed all of my morning meetings getting in 5 hours later than I was supposed to and had to change to take a later flight the next day to get them back in which cia time another $150.

It was very difficult to stretch my knee out and I am very short. I also had a torn tendon in my knee which made it extra uncomfortable anyways. My husband is 6'2" and I can't imagine him flying in that plane.

I was late from Jacksonville, FL but the limited interaction I had with the Philly crew was great.

Awkward carry on process. Forced to check all carry on. No overhead space of worthiness. Left delayed, but made up the time. Crew was amicable.

Delayed 4 hours from Charlotte to Nashville. Could have driven there faster. Information provided by AA was sparse.

Gate change was a little tough but it was a good flight otherwise

Great flight, great service but most of all- our luggage made the trip with us.,
