No wifi, seems to be very common with Southwest currently. Everything else was normal.

Poor customer service, no accommodation for passengers when the flight was delayed over 5 hours.

Friendly crew kept coming by to make sure all was ok, provide additional refreshments, etc.

No gluten free snacks. Seats felt worn or bare bones even though it was a new 737 MAX 8.

I'm glad it wasn't only 75% full because I could get a good seat

Check-in, Boarding and flight were smooth. All the employees and crew was very nice and funny. They gave the kids crayons and workbooks to keep them occupied which was a big win. I’ve flown Southwest many times and that’s the first time I’ve seen that and it is a great addition.

The Southwest employees (all two of them) were very nice and cheerful despite the fact the line to self-check a bag (simply drop it off) was hundreds of people long. Thank God I arrived early to the airport because I stood in this line for at least an hour. Once on the flight that had been delayed by an hour, we had no Wi-Fi and thus no entertainment. Finally, I hope the investor strong arm tactics against Southwest pay off in a short-term windfall to your C-Suite because the rest of you are screwed. I have been a faithful Southwest customer for 15 years due to everything you just got rid of. I'm flying to Idaho and Washington in October, both places I used to simply book with Southwest without a second thought now with Frontier (Washington) and United (Idaho) because they offer everything the "new" Southwest does but cheaper and at better times, destinations, etc. This really makes me sad...

It was really nice! I appreciate the gate attendant allowing families with small children to board early on in the process… that was very helpful! The internet service didn’t work with the app I was trying to use even though I paid the $8… other than that it was great! Oh and I should’ve asked for the whole cranberry cocktail can. That cup was about 2 sips…

I liked the boarding process with our loading group and numbers. I disliked that I couldn't guarantee our seats together. I didn't like that the Internet costs $8/ flight, but did love all the inflight options available through their app. I disliked no charging station at my seat for a 3+ hour flight.

Great! Although the flight was about 40 minutes delayed, the crew did a good job getting everything boarded quickly and efficiently.

The aircraft pumps heat into the cabin in warm weather. High, prolonged discomfort. Not okay to put customers through that. Time to upgrade their fleet.

I would love it if Alaska Airlines brought back the complimentary beverage service on short flights

the flight was fine, But I paid extra for an Aisle seat both planes and did not get what I paid for when you pay an extra almost $80 and do not get the desired seats it was frustrating I don't fly much because of my legs need more room. thank you for your attention to this

Our seat assignments were mysteriously changed such that our boarding was delayed when they tried to fix it, but to no avail. It took more than 15 min. before we sat down. Then the catering delayed our plane for 35 min.

The seat was comfortable, but I paid for upgraded seats and they did not state that there was no outlets for devices.

My experience was significantly impacted by problems in Seattle with luggage check-in. Apparently, Alaska Air was significantly understaffed in this area for the number of passengers for that morning or they had issues with the machinery processing and loading the baggage. Upon tagging my suitcase, I was sent from one drop-off area to another and yet a third on a different floor. The line to do most of this was VERY long and moved quite slowly at first--I just barely made it on time to catch my flight even. though I arrived at the airport an hour and 40 minutes early. Then when I arrived in Charleston, my bag didn't arrive on the carousel with other luggage and I had to spend extra time tracking it down.. The relative who helped me out at SEATAC said he had never seen the airport so backed up and he travels out of that airport frequently. It was a very stressful experience, and very disappointing.

all crew, pilots and attendants were fantastic. Both to and from flight to SEA, attendants went above and beyond.

I was totally disgusted at the stewardesses supplying the three passengers in front of us in the exit row with multiple rounds of booze. They were loud and inappropriate using profanity to share stories. Our 3 and 7 year old he’s d it as well. Just flat out inappropriate and amazed AA wasn’t implementing a drink limit policy.

Spent extra to choose my seat. Found a window available so grabbed it. They did not mention the row didn’t recline. Had over 5 hour flight stuck in a straight back chair. Traveling for funeral - needed to rest and couldn’t get comfortable (row infront of exit😒 should have realized but wasn’t thinking I guess).

Our Alaska airlines flight eas cancelled 2 days in a row. They did nothing to sccomodate - no hotel rooms or meal vouchers. We were left on our own. We switched airlines to fly home. I would give this serious consideration before using this airline again.

We got stuck on the tarmac taxiing after landing early so we didn’t get off the plane until an hour later than we thought we would

Bus to plane was delayed for no apparent reason and our luggage was still on the belt when they shut it off. Took about 20 minutes to turn it back on to get our luggage.

I haven’t flown economy in over 20 years but it was not bad. Room by my feet for my bag and seat was roomy enough. Surprised in a good way.

I am still at the Airport! Delayed Delayed and Delyaed

Second flight in a row where the entertainment system is broken. 5 hour long flight with no entertainment and flight attendants did not seem interested in resolving the matter. Very shocked to be treated this poorly considering I paid for a first class experience and have Diamond Medallion status.

The service from the flight attendants were of supreme quality. They greeted and treated everyone with a wide smile. This is totally absent nowadays. Kudos to them!!!!

My seat had no padding, it was literally plywood with a plastic cover. I could not change seats on my 10 hour flight. My excitement for this trip helped me deal with the pain.

The pilots were good. Disappointing when planes don't have electrical ports

The flights were on time- Great service Would have liked more options for food choices.

No complaints - left 20 minutes later than planned but still arrived on time.

the whole trip was smooth, and as comfortable as flying is these days. flight crew was friendly and very courteous and helpful.

Yet another flight in which beverage and snack service was skipped. Other that that, firmly mediocre. Landed early, to gate late due to congestion at the gates. Airline's fault or airports fault: unknown.

The flights were on time which was great give. It was holiday travel season and there’d been some weather issues. The only complaint and this is every time with United is the terrible seat design. The head rest is not built for comfort and having my neck bent forward for a cross country trip reminded me while I try not to take United flights as a rule.

This was a very average flight. The seat was out of alignment so more uncomfortable than usual. The cabin felt not well maintained. But I safely got where I needed to go.

We had a 90 minute delay due to equipment failure that was detected just before we took off. United rebooked my connecting flight.

Dinner was okay but the breakfast was not eatable on the flight San Francisco to Zurich.

This was a Lufthansa flight. Disappointing main meal. Very rough over Canada and arrival at FRA. IFE was almost unusable.

Poor seating comfort, seat cushion too thin, very uncomfortable. My luggage didi not make the flight due to equipment change. At least. United had it delivered the next day. I was without my toilet items for one day.

Flight cancelled because of the grounded 737s. United was good about it and got us onto a later Alaska Airlines flight to Oakland (not San Francisco as originally intended). Had to go through security again and my wife dropped her MacBook Pro, which broke, a $2,500 whoopsie. But we made it home.

I liked being upgraded to first class. The flight was a redeye, so I did sleep most of it.

Luggage took too long go get off plane in Knoxville. Was almost 45 minutes after the flight landed.

Awful, tons of delays, I got into Chicago multiple hours late meaning I hit the very traffic I tried so desperately to avoid. Just empty apologies from American Airlines text alerts. Trash behavior from a trash airline.

The boarding was as always, the crew tried their best but not enough. The food was a disaster I had dietary restrictions that were half met because the company did not loaded the food for the flight. The entertainment screen was fine but content was not and also they removed the free messaging option from the flight and they charged 30 dollars for that crappy bandwidth. This flight is not worth the cost and the company is going down on quality.

Poor seat in rear of aircraft Food at Admiral’s Club Terminal D at DFW inedible

As smooth as you can expect. Some issues with boarding because the previous plane took forever to deplane but overall, a good experience.

DFW-LHR Toilets not kept clean Too cramped. Aisles so narrow crew were constantly banging into people on the aisle seats. Even then, the carts used are reduced width. Other than that it was a decent flight on both legs

Excellent customer service at check in at Austin flight to DFW and excellent customer service from Karren in terminal B at DFW.

Multiple gate changes and significant delay leaving DFW. Made for a late arrival

For the price of the ticket you get nothing. The plane had 1 bathroom in the back and when the flight attendant did service no one could use it. No announcement just was told to go back to my seat. Ridiculous and rude.

American Airlines no longer has Bischoff biscuits. This is intolerable.
