Flight was fine. Only thing was flight was delayed nearly 2 hours. Flight was originally scheduled to depart at 7:50pm but didn't depart until 9:50pm. I got home around midnight. It was later than desired and I had to get up early next day to take kids to practice. I have noticed that last flight of day on West Coast for Southwest always tend to have delays.

Wasn't expecting this, but, we actually ended up getting assigned to the first row of seats!!!!! The extra legroom came in handy

Just crazy with times being pushed and pushed and pushed and gate crew at Philly super rude and unprofessional with many under stress with delays.

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.

For my birthday trip this was my second time ever flying, this trip was the best.

I really wish that SW would ask anyone with a carry-on to wait while those who don’t have to access the overhead bins are boarded. Then, reverse that when the plane arrives. Those without the need to clog up the aisle retrieving their bags from the overhead bins wait for those exiting the plane without needing to clog up. The aisle.

We boarded the flight and set two and a half hours on the jetway. Would have been better if they had not boarded us at all. Plane was hot and it was limited ability to access the restrooms or get a drink of water. Very unpleasant experience

The actual flight was great! The 3 hour delay not so much.

Southwest is a garbage airline and the people who fly it are garbage people.

Boarding was easy. Plane wasn’t crowded. Plenty of space. Flight was on time. Crew was pleasant.

This a short easy flight. No food or drink but that was not an issue since we were only in the air for 35 minutes.

No Internet, no backseat screen, no nothing. I bought a Delta ticket and ended up on American Airlines. How did that happen?

Connection flights should be spaced out farther because too close I missed my connection.

The flight was way too HOT! And the plane did not have any in-flight TV entertainment.

Easiest airport experience ever in my life at MSP with Delta check-in and flight attendant gave us a bottle of champagne in celebration of our 10-year wedding anniversary, so overall amazing!

The gate attendants and the crew were terrible. Because of high winds, they needed to carry more fuel, so they had to get volunteers to take the next flight at 6 am the next day. They did a terrible job of it - our flight ended up taking off just under 3 hours of the scheduled time. I hope to never fly Delta again.

Great. Seamless. Check in agent at kiosk international was amazing and extremely helpful.

Great service. Great staff. Boarding was a little slow, but I think there was a service dog slowing things down.

We splurged and decided to fly first class. Seats were roomy. But flight crew arrived late to the airport. That delayed our flight. Most of the passengers had to try to make connections flights. I felt bad for them. We checked 4 bags. We got three from the baggage claim carousel. 4th one was lost. Delta online help wasn’t good. Baggage claim staff were sympathetic and nice but we waited around for almost 2 hours and it had t been found. They did find it several hours later and we had to drive back to airport to retrieve it. I won’t be splurging on 1st. Lass again anytime soon. I think we got worse service. I am also not a huge fan of delta but we have family in ATL so we don’t have a ton of choice. What should have been an easy flight turned into a stressful event due to flight crew tardiness and baggage mishandling.

My flight consistently said it was on time and the plane didn’t arrive until after 30 minutes after take off and nothing was announced to passengers

Like the fact that the boarding was expedited. But the delay and chaos around the onboarding was not appreciated.

The flight crew were very helpful. The seats were very close together. There was barely room to sit without touching the person next to you.

It was great. All the crew were professional and nice.

The flight I was supposed to be on was supposed to take off at 1:50 from State College. It was delayed over and over and over again until somehow I had to rebook on a flight that was supposed to have left State College at 8 am that morning but didn't end up taking off until almost 6 pm. Not only was this completely unacceptable, the "token from United" was a 15 dollar meal voucher that has to be used by today. I would personally like some miles added to my account for this inconvenience. I was in transit for 8 hours from the time I arrive at State College Aiport to when I got home. I was supposed to be home at 3 pm and I returned at 8 pm. Unacceptable. I have not been on an on Time united flight in nearly 5 years.

newer aircraft, ability to connect my headset via blue tooth for entertainment.

Miserable. They moved my seat, but canceled the next leg of my flight. I resolved the issue at my transfer, but that resulted in lost luggage that has taken days off my schedule with no resolution. Worse, they fail to interface effectively with Lufthansa, forcing me to bounce between two equally useless help desks. The apps are unable to handle the situation, the bag dropped off the tracker, and while the call centers are polite, they do not provide written information to assist with cross-airline communication.

My husband and I recently had an unfortunate experience with Lufthansa. At the Philadelphia International airport, the ground staff refused to board us because we didn’t have a current visa stamped on our passports for Frankfurt. We completely understand that this was our mistake. we should have double-checked the visa requirements before our trip. However, the issue that upset us most was how the situation was handled by the staff. They told us they would mark it as “boarding denied due to visa issue”, but instead they recorded it as “no show”. Because of that incorrect entry, our return flight was automatically cancelled as well, which caused additional stress and expense. Mistakes can happen, but we expected more transparency and accuracy from a reputed airline like Lufthansa. It would have made a big difference if the staff had been more careful and considerate in documenting the situation correctly.

Everything was good, except the seats in economy were so close together, you could barely get out when the seat in front of your was reclined. If the airlines keep jamming in more and more seats, it will become intolerable. I will look for another airline that considers customer comfort and does not keep adding more rows of seats for more profit.

Flight attendant moved my bag without notifying me and was rude to me when I asked him about it. There was no reason to move it.

Flight was on time, crew were excellent. For some reason our originally selected seats were changed. We had to re-choose our seats when we checked in online and options were limited. One of our two checked bags we placed on the wrong carousel. It was only be shear luck that I saw it. That cost us 20 minutes of wasted time. So much for the “priority” tags. They are meaningless, and have been ever since they were implemented. I wish you would do the save some money and stop using them.

Thought the economy premium experience would match that of the Amsterdam to Boston flight. Aircraft was older: chair didn’t lean back. I had to buy a blanket, which on the flight over was complimentary. Flight crew seemed disinterested all around.

I propose enhancing the legroom across the entire cabin seating area and expanding the snack selection. The airline companies should prioritize customer needs over the extravagant and unjustified salaries of upper management.

KUDOS TO ALL THE CREW PROVIDING ASSISTANCE WITH PASSENGERS ON A WHEELCHAIR. ON BOTH FLIGHTS THEY HUSTLED TO TAKE MY RELATIVE TO CONNECTION ON TIME. THEY DESERVE A LOT OF CREDIT!

see my previous response about being kicked off the flight and having to fly the next day, ruining a planned vacation tour.

They lost my luggage and refuse to help. Terrible airline. I've never experienced worse customer service in my life. Pretty much just told me too bad that I lost all my luggage, not caring that I am stuck in Europe for 2 weeks with absolutely nothing.

I especially liked the lead crew officer. His boarding and safety announcements were made with a bit of novelty and humor. The flight also left the gate 10 minutes early and we landed about 20 minutes early… It was a delightful flight…

The flight departed more than 1 hour late. Leg room is bigger than most airlines

terrible. Because I felt very unwell during the flight. How do they leave a woman alone in the middle of 2 men? an obese man who was falling on top of me.

I booked this flight using JetBlue points and I was just so happy. The plane was so clean, I had every need met. Thank you!!

As with all airline's seats, a little more padding would appreciated. Especially on longer flights.

Id like for them to not have lost my bag. And maybe be a little nicer to me, given the fact they lost my bag.

Seats are uncomfortable and my impressive barely 5’10” frame meant my knees were touching the seat in front of me. My 5’3” sweetheart found the seats equally uncomfortable The crew were transactional. The food edible. The entertainment manageable. The boarding process efficient. The experience okay.

Hey as long as you bring me back to earth in one piece I’m good! Otherwise great flight smooth take off and landing good staff Only thing is the staff at the back of the aircraft chatters a lot it’s annoying at times but I’ll let that go because they are very sweet overall.

The airline company should manage their crew for the plane on better schedule so people don’t have to wait in the plane. And this flight that I had had no snacks offered, and if you would like a water, you had to come see somebody and ask for. If airline would let people know that they are no longer providing or offering any food. At least people could bring their own if they wish.

On time departure was much appreciated. However, as a frequent flyer and American Advantage member, I was as disappointed not to get an aisle seat.

Flight was cancelled due to a myriad of operational issues. You guys really suck

Our gate was changed several times, and the gate agents were just as in the dark as all of us in knowing when our plane would arrive at PHL.

mechanical problem delayed more than 2 hours on the run way.

The boarding process was slow and we had a delay on the tarmac, not the fault of the airline. They had ZERO food options available for purchase which shouldn't happen.

Plane was delayed for 3 hours, due to situation within aa control. Information was shared poorly. We sat on tarmac for over 40 minutes after the 3 hour delay.
