Southwest has inacted unfriendly customer policies like other airlines. Watch the fine print very carefully if you are having to alter flight arrangements. Rules are now complicated and very stilted to travelers sacrificing travel funds (unlike before where the simple, straight forward flight change policy was worth the extra premium for ticket price.) On the positive side, SW Flight crews are still wonderfully helpful.

Southwest has inacted unfriendly customer policies like other airlines. Watch the fine print very carefully if you are having to alter flight arrangements. Rules are now complicated and very stilted to travelers sacrificing travel funds (unlike before where the simple, straight forward flight change policy was worth the extra premium for ticket price.)

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

The flight was late. The crew was rude. There was no food. Cramped and uncomfortable. Nothing about this flight was good.

It was great. The gate staff were very helpful in Portland when my son forgot his rolling bag and had to go back to get it just in time to make it on the plane. We really appreciate that. Great job!

This leg was much better, but we did have to have a 3 hour lay o er after coming from a very exhausting hiccup with our flight from BNA to Den

Southwest is kind of a slum airline. It’s gotten more expensive over the years for less and less service. I am a Southwest Chase Visa card holder and was forced to choose a seat in the 26th row in the middle seat. However my wife who is a rewards member but doesn’t hold a card or anything else, gets randomly assigned a normally paid seat in row 6! How does that work?

It was as expected and I was grateful for the wheel chair help and ease of use.

Tight seats. Be prepared to sit in the middle if you are in boarding group C.

This was a connecting flight for me and I had already traveled for 7 hours. First, the Pilot didn’t show up and then the gate changed twice, after which the flight was rescheduled for 2 hours later. This made me late and I had to make other transportation arrangements to get home to Astoria another 1 hour & 45 minutes away. This cost me $250 more than it should have. Will not fly southwest again.

Long layover in Chicago. Wish that could have been lessened.

It was about as poor as it could be!!! Delayed not once but multiple times

Flight there was massively delayed but never updated on the app. Flight home was massively delayed but also never reported until after we arrived at the airport.

The inside of the airplane was to cold and there was condensation dripping down on me. We were late taking off from Portland to Medford and I was miserable.

The flight left almost an hour and a half late because Alaska Airlines didn’t have anyone there who was qualified to drive or tow the airplane from its overnight parking spot to our gate. Because of that debacle, MANY passengers, including me, missed our connecting flights.

I have a good impression with the staff's friendliness and helpfulness and with the confort.

Several gate changes and then the plane kept getting delayed. The delay is understandable but this constant gate change I think twice or three times is just ridiculous.

The flight crew home was so, so friendly and HILARIOUS. I’ll keep flying Alaska like I have for the last 30+ years!

I needed a wheelchair due to a fall over Thanksgiving and everyone was incredible, especially the Alaska gate agents and crew.

My baggage was very late to baggage claim. Alaska possibly put too many flights onto the same carousel at PDX. So I got home much later than expected. My aisle seat couldn't comfortably fit my personal item. It's one of the frustrating, silly designs where the aisle has much less under seat room than the other seats. The crew on this flight was excellent. Everyone was as helpful and friendly as you could hope for. We were pretty close to on time, but the baggage claim effectively ruined that for me.

It was my first flight with Alaska due to the destinations I travel. Definitely will travel with them again. Lovely experience! Check in, gate attendants and flight attendants were exceptional!

First flight was delayed which resulted in missing our connecting. As a result class was downgraded to economy on a later flight.

Unprepared to rebook a flight of people. Uncommunicative. When I received updates in the app it was well after the announcement in the hold room. Offered a single $12 meal voucher, not enough for a sandwich at DEN, for a 17 hour delay. No one was able to explain their meal or hotel reimbursement policy for this cancellation, just handed a card to call the Help desk. My previous flight went through several delays and was finally cancelled, without explanation. The customer help desk closed while there was a long line. I then waited in line for a gate agent almost an hour while simultaneously on hold and trying to text with a remote Delta agent. Communicating with the text agent was almost impossible; they could not find any flights that got me back to my original city before the following evening. Kept offering itineraries that did not get me back to my origin airport or involved additional layovers. In 50 minutes on hold, never got through to an agent by phone. Finally spoke to one of the gate agents who was able to rebook on a red eye that had only one stop and got me back in the afternoon the next day, rather than late evening. Later by email, Delta offered 10,000 loyalty points for the inconvenience of the cancellation. The crew on the red eye flight were delightful. I don’t remember any food or entertainment on that flight.

I have Precheck. Flew HPN to DEN and return this past weekend. Delta didn't attach my Precheck number to this trip. So it was waiting in general line especially in Denver. Unavailable.

worst flight ever from Delta, it got delayed and kept on delaying..

Fast, lovely scenery, great info on the Delta flight screen about landmarks we were flying over. Great landing!

Delta needs to step its game up get a more reliable internet service. Internet service was non-existent for this flight.

Terrible. Four hour delay because Delta could not find crew to man the aircraft. Terrible communication. Terrible insight into the delays. One of the worst flight experiences I’ve had.

Mechanic delay in addition to a 2 hour change in takeoff time was frustrating.

The Pilot was one of the best I've had, very informative about turbulence and got us to our destination early

Friendly boarding crew. Better could have been a bit more substantial food for this 3 plus hour flight.

Had a one hour delay due to mechanical issue. I didn’t think I’d be able to make my connecting flight, but they waited for me and greeted me when I arrived to help things run smooth.

Staff were good. My seat was in need of repair, but for a short flight was not problematic. Usual basic snack and drink setup that you'll find on any US carrier. Over, a decent, basic flight.

I will never book a flight through Cheap fare. They booked me from Portland Main . And would not give me a refund, so I bought 2 tickets one for 299. From Portland Main to ORD. Then I had to buy a ticket from Oregon PDX to ORD that was another 440. So Just so you know they even told me it was there fault but no refund. Bad bussniess. I did inform United but they said they couldn't help me due to the fact I booked through Cheap Tickets. Never again. And I'm spreding the word. I let everyone know at my 50th class reunion

Pilot Erika DeLong made us feel safe and at ease in a frankly scary time to be flying. Her warm smile and greeting and excellent command of the aircraft in foggy bumpy weather helped us all to calm our nerves and get us home safely.

Not enough room between rows and food was gross. $160 baggage charge?! Never again.

East Lounge in Denver was terrible. Turning away active military on orders? Really? Sad.

Clean and plenty of room for handbaggage. Leg room was cramped compared with the 777 from Frankfurt.

they made me check my carryon. There was space in the overhead bins.

Cramped and uncomfortable seats. Not enough room for 6’2” person such as myself.

Pretty turbulent, but not anyone’s fault. They got us there. Impressed that they carried on with a drink service.

It was ok. It was expensive to check 2 bags ($75.00 per bag), and then it took a long time to wait for shuttle to take us from one terminal to the terminal where the plane was taking off at LAX. And all of this for a flight where we had to pay for any food or drink that was not water.

The delay was ridiculous because nary a word escaped from the gate attendant regarding our flight status. It was a complete joke.

The seats were awful, hard plastic covered in sheet vinyl. The airline tries to scam you into paying extra to get seat together when the flight wasn’t full. They were going to separate a family with young children but my wife who had a row to herself gave up her seat so the young mom could be with her young boys. I’m never giving this airline my money again.

The worst flight of my life. Never will I fly frontier again

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

I ended up paying $70+ dollars to for a carryon because the website is confusing and misleading. I now realize I did not need to pay that. I request a refund. I will pay extra to other airlines and not fly Frontier again.

Although we received an email from Kayak AND the airline, turns out we were not on Frontier’s manifest for the flight. We had to purchase tickets at the gate. Not sure where this transaction fell apart, but it did. We are now disputing the charges for the SLC to PDX flight originally booked through Kayak.

While booking it was not obvious that I had to pay for carryon. Realized it only during check-in. Overall, meh!

We understand and comply with Frontier’s bag sizes. We’ve had some problems in past while having to await other passengers who do not understand the baggage restrictions or have not prepaid and that is usually our biggest concern (others delaying us) with flying Frontier. Flying OUT of ONT, however, has always been a great experience. I’ve also noted even on delayed Frontier flights very knowledgeable pilots who manage expectations well.

Seats are cramped and uncomfortable. You have to pay for everything and it is very expensive.
