Southwest boards more efficiently than the rest in my opinion. Boarding should start at the opposite end of the plane from the door and preferably window to door but instead it's front to back and takes forever when each passenger stows a bag and blocks the rest. I have seen the back to front work well in other countries.

Here’s the part that confused me the most. JetBlue flies only from terminal 5. Delta (at least) arrives in terminal 4. Be aware that there is a lot of walking to get out of terminal 4, then you board the sky train, then you walk more, and finally get to terminal 5. There, surprise! You have to go through security again. At JFK, some security lines are ridiculously long and slow. It’s very annoying that transit passengers must go through that again when moving between terminals. One more thing related to terminal 5 where JetBlue flies - there is absolutely nowhere to sit and almost nothing to eat before going through security. The security lines were better organized though and it didn’t take that long.

Chicago airport is super chaotic. We had come in from an overseas flight and were required to get our checked bags at Baggage Claim and recheck them for our next flight, which took a while. Then after going through a LONG customs line (again) and rechecking my bag, I was told to take a shuttle to a different terminal for my final flight. Even though I never left the building and had no access to the outside world, I had to go through security AGAIN (boots off, dump out my water, wait in long lines…) My advice is to be sure you have at least a couple of hours between flights to deal with the insanity.

Make sure the flight you select has more than 3 hours as time allotted for transiting to another flight. Most of United Airlines flights get delayed and if you don’t have enough time, you’ll be missing the next flight for sure. Have extra budget for shelter expenses because most of the economy tickets does not qualify for shelter accommodation/ voucher when your flight is delayed.

My experience will Southwest was good. I wish there was more entertainment and the boarding process was slow at time but other than that my experience was great definitely will be flying with SouthWest again.

Flight was delayed by 2 hours, meaning that a flight to Dwnver which should have arrived at 11pm came into the airport at 1 am. Made for a very long day.

I think Southwest is the number one airline that anyone can fly I have flown for the first time Frontier and what a joke and their customer service United was a very strange experience I'm only sticking to Southwest from here on out for sure

Great job! My family doesnt fly often but we felt safe 100%

Great job Southwest! My family doesn't fly often but we felt safe the whole time.

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.

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

Crew was rude, flight was late, wifi didn't work, no food, basically nothing about this flight was good.

It was just okay, no frills, basic transportation with no luxury. No screens on the seats, no water or drinks on a short flight. Full flight but at least it was on time.

Flight was constantly delayed with significant changes in time, it was supposed to get to Colorado Springs at 8:30 PM but it got there after midnight.

Everything about this flight was good except for the very end when I reached my destination. Everyone from the tune to the wheelchair escorts were great with the case were great but I miss you with people at the check in this at the very end. I need help from the chicken desk because I forgot my pillow on the plane The female worker at the chicken desk said that they found my pillow and she was going to retrieve it for me. She left a 30 minutes without any update and her so she saw me walking back and forth waiting for her and they didn't even bother calling her or radioing her for any updates. They were busy because they were behind schedule and they were overwhelmed but thanks because at least glanced me and try to give me an update just a quick radio check or phone call. I don't care about the pillow but if you tell me to wait, I waited for at least half an hour before I said something and I just left because they wouldn't bother talking to me so I could, so everything's going in the review. I took pictures of the two men that were left working at the check-in counter. The totally ignored me despite the signals I've been giving them. I don't see any offers in the kayak review to add pictures or screenshots so I'm going to post another review I don't know their name but I'm pretty sure Delta will find other names when they see the review. Google with pictures. There was another guy at the chicken counter bring an orange workers vest who finally left after telling me that the girl that was retrieving my pillow is working the gates now. That would have been if they just told me that's what happened. But I had no update. Make me wait for nothing. Thank you Delta airlines!

We had a great experience with Delta. They helped us from the start at the kiosk all the way to our final destination, including help reassigning and upgrading our seats free of charge at the gates, escorts with the wheelchair for my brother and even getting our luggage at baggage claim for us. I also had special help because I forgot my pillow on the plane. The wheelchair escort contacted for associates at the check-in desk all the way back to the plane and retrieved my pillow for me.

Crew was real good, flight was smooth and came in early.

The CRJ-900 was clean but the overhead air vents were broken in our First Class row, making the cabin very hot until about 30 mins into the flight. The flight attendants were both extremely apologetic and accommodating though so that is why I rated the flight as very good. They checked on us many times and truly showed they cared. The snacks for an hour and a half flight could be better. Would be nice if there was a small plated meal over convenient store snacks. WiFi also was not working. And it would be nice if Delta had adjustable headrests on these planes.

New high end luggage ruined/zippers broken, items missing. All happened on return flight from msp to mso. Do better! Not store bought luggage but high end personalized ogio custom embroidered luggage. Total slap in the face ontop of an extra luggage fee that took me 3 hrs on chat to resolve.

It was as good as it could be. Flying is not a pleasant experience these days.

The plane was old and thus the seats were not good. No cushion left whatsoever, and it all was a bit worn out.

I was in Comfort and we didn’t get any drinks, chips or anything! First Class got full service on the flight and Comfort got nothing. Seat was horrible and uncomfortable

My flight was delayed by 4 hours in 30 minute increments. The gate agents were amazing but the communication was not. We were told that there was a maintenance issue but they didn't know what it was. That didn't inspire confidence. Then they said they found it and it was fixed and the pilot just needed to sign off. Then the pilot needed to talk to the other pilot from the arriving flight and we'd be fine. Then we were waiting for the pilot to call back. Then the maintenance issue wasn't fixed. Then they decided we were getting a new plane (why didn't they decide this earlier??). Fine. But then they announced we were changing gates AND terminals. And we were boarding in 20 minutes. So we all had to run to the new terminal gate. We could have taken off at that time, but we then had to wait for all the people who rebooked on a different flight to book this flight again. That took 30+ minutes because there was only one gate agent. When everyone ditched this flight, I saw it as an opportunity to upgrade to comfort. Delta, the greedy jerks they are, charged me $121. After their delay, their fault, their issues, couldn't even discount an upgrade. They only handed out $12 meal vouchers for the delay. I can't even get a snack from starbucks for that.

The crew was very inconsiderate and rude. My flight was scheduled to depart at 6:00am. I received a call from the crew at 5:40am, asking if I was going to make the flight because I was the only one that hasn't boarded yet and boarding ends at 5:50am. I let them know that I will be at the gate in a few minutes, before the 5:50am cutoff. When I arrived at the gate at 5:45am the gate was closed. Departing early on last minute notice without having all passengers on board is inconsiderate and unprofessional.

The flight was delayed by a hour and I wish they had communicated it sooner. No issues on the plane, it did take a while for food to come.

Know that the movies that you are going to be offered are the oldest be rated movies they could possibly get. They may have one or two new movies that they keep advertising but when you’re flying 15 hours, there is nothing to see past the first new movie.

Staff could’ve been a little more cordial. The men were much more friendlier than the women. My daughter and I also missed the 2nd to last meal as we were sleeping but that is on us.

Great staff. Clean plane, but we were delayed for more than an hour due to maintenance issues and had to board another plane.

I was very disappointed with my experience at the United Airlines baggage check. The representative was rude and unhelpful. I was required to remove approximately 1.5 pounds from my two checked bags, even though it was a very small amount over the limit. The interaction was unnecessarily unpleasant, and I expected much better customer service. I hope United will review this incident and provide additional customer service training to its staff.

No extra snacks were available. Meals quality is terrible. Crew was not friendly.

I was exhausted from a long day. The flight was smooth. The first flight during my 3 week travel that took off on time.

Agents at gate were not immediately available to solve problems and once they did they didn’t fix all the fight connections

1 flight cancelled Had to fly out of different city Flight at new departure city was delayed 3 hours causing us to miss connecting flights. By the time we did make it to Prague our luggage did not. Had to wait day and a half for luggage to be delivered. Customer service was not good. Agents did not arrive at gate until 5-10 minutes before boarding

I needed internet for critical matters and it never worked.

I found the seats ergonomically uncomfortable forcing the body to seat slightly hunched. For a short flight I worked on adjustments but for a longer flight, it would be difficult.

The seat was not even cleaned. It has full of cookie crums probably from last flight's passenger. Its basic expectation that, seats are clean.

Crew was great! Food sub-bar, tepid & flavorless. No snack options on trans-atlantic flight. Premium Economy seats ok, leg rest wouldn’t stay in place.

The planes can use an actual cleaning. The armrest and seats do not appear to be cleaned on this one and most other planes.

The flight attendant was very polite and attentive. The food was good.

For some unknown reason, my checked bag didn't arrive at the same time. I got to my destination about 30 minutes late (5pm) and my bag was delivered to my hotel at 2:06am.... in the past 4 flights with AA, they been delayed and I've missed connections and my bags. Poor service.

Flight was delayed…once landed at ORD, no gates were available so made us wait for 56 minutes after we landed to let us out of the aircraft!

Entertainment system did not function. USB ports did not function. Wi-Fi did not function. Terrible trifecta…

I cancelled this flight 2 days before departure but I followed your texts and emails and IF you were correct this flight turned into a nightmare.

My flight was delayed twice. The first time because of “plane maintenance” and the second because the previous flight who supposedly “arrived early” took an obnoxiously long time to get off the plane. Total delay was over an hour for no reason. Not to mention your airline repeatedly changed our gate from one end of the terminal to the other. Not very happy about this experience. My previous flights with American haven’t had this many issues.

It was awful everything about it terrible I will never ever ever ride it again

It was awful ....my first time flying on it and I will NEVER fly it again ....everything about it was terrible .....most especially the flight attendants

Crew was kind of grumpy and there was no beverage service at all. Sodas were $4. Disappointing.

There weren't enough employees at check in took awhile to get bags checked. There wasn't a wheel chair for me, I was sent to someone who turns out to work for a different airline, if My flight hadn't been delayed I probably would have missed my flight as it was, by the time I arrived at my gate, they started boarding in about 15 minutes. I don't know who took me to my gate, definitely was not the normal people who take passengers to the gate. I'm guessing she may have been in a management position. I wish I knew her name, she went beyond to help me. With that said everyone was kind, and were doing the best they could. So, I choose to say it was an Adventure, stressful start, but good. In the end went well. The situation was not only difficult for passengers but the employee's.

The staff at the check in counter was so rude. Made you feel Incompetent

Frontier scheduled a 40 minute connection in DEN. What they failed to mention was that they “close the doors” 20 mins prior to departure, which means you only have 20 mins. Not enough time. Possibly against DOT regulations. Filing complaint.

Flight was scheduled at 9:40pm. Got delayed to 10 am, the next day. crazy

The bag check, flight check-in, and onboard experience convinced my wife and me that we will actively go out of our way to avoid flying Frontier Airlines in the future. At bag check, we were informed that check-in could only be completed via the Frontier mobile app. Unfortunately, the app was extremely frustrating—sending us through repetitive, confusing loops that repeatedly forced us to decline add-on services with nearly every click. While most airline apps upsell, this one felt intentionally exhausting. As the process dragged on, we became genuinely concerned that my phone battery would die before check-in could be completed. We approached the bag check staff—who were standing together talking—and explained both our frustration and our predicament. They laughed. Later, my wife described the interaction as “gaslighting,” which felt accurate. We were then informed it would cost $25 per person simply to have our boarding passes printed. From that point forward, the tone of the experience was consistently hostile. The bag check employees were condescending and combative, behaving more like bullies than customer service staff. Unfortunately, that same attitude continued onboard. One flight attendant argued with me when I attempted to stow my backpack in the overhead bin. I explained that we had each paid $75 to check our bags specifically so we would not need to use carry-on space and could have adequate legroom. She demanded to see my ticket, pointed out that it said “no carry-on”—which I acknowledged—and I reiterated that this was precisely why we paid to check our bags. Her response was, “I don’t make the rules.” She then walked away, but not before asking if I “truly wanted to fly back to Chicago today?”—an unnecessary and unmistakable threat. It is also worth noting that despite booking our tickets together in the same transaction, we were not seated together. Upon our return to Chicago—where we could once again sit together—we compared onboard experiences. We both remarked on how unhappy the flight attendants appeared and how each of us was separately asked whether we would like to purchase a beverage. We declined. At no point was water mentioned as an option, leaving us with the clear impression that even water came at a cost—or that complimentary water, if available at all, was deliberately left unmentioned. Overall, the experience was shocking and deeply disappointing, but it was also a profound learning experience—one we will not forget and will not repeat. -Steve

Plane was hot and miserable and the crew was rude!

12 hour delay required getting on and off plane 3 times - would have at least liked to have been offered a snack or drink
