Verified travelerFlew with American Airlines-Sep 2026
They boarded us as usual, but then we had to wait on the plane for a long time until for some reason they had to switch flying crew. The plane was newer, so the seats were semi comfortable in economy class and everything was working. One good thing the crew on the plane asked people to stay in their seats and let people with connecting flight to go first as they were getting late for connecting flights to go further on their destination.
Verified travelerFlew with United Airlines-Oct 2026
Check your watch carefully! I was afraid I was going to be late for my flight because I thought my watch said it was an hour later than it actually was. Also, if you need special services, like a wheelchair ride between flights, be sure you make it at the same time you make your reservation and get a confirmation for it.
NicholFlew with United Airlines-Oct 2026
Ensure you leave yourself enough time at the airport. It is a busy airport so can take a little bit to get through security if you don't have TSA precheck.
GeorgeFlew with American Airlines-Oct 2026
Book rental cars in advance. Do not try to reserve a rental car at the counter, at least with Hertz.
MargaretFlew with American Airlines-Sep 2026
Make sure to check flight for gate change frequently.
PaulFlew with American Airlines-Oct 2026
That you don't get much help making connections to a domestic flight after an international flight in Philadelphia. At least that was our experience. Get assurance your bags have been loaded. Or bring a carry on bag rather than book your luggage. Maybe Philadelphia is just a confusing airport, I don't know, but most trouble we've ever had.
NFlew with United Airlines-Jul 2026
You need to check your own bags in, meaning you wait I line to print the ticket, put the tab on yourself and then go to another line to make sure the suitcase gets placed on the plane and under the 50lb weight limit. A lot of back and forth.
RobertoFlew with American Airlines-Apr 2026
It's always best to arrive early if possible in the event that there are any delays with TSA.
Verified travelerFlew with American Airlines-Feb 2025
West Palm is an easy airport to navigate. Not big and getting luggage is quick.
FernandoFlew with Spirit Airlines-Sep 2024
Give yourself plenty of time, especially if you are parking off property.
Juan CarlosFlew with American Airlines-Sep 2024
Watch out for waiting conexión time is you arrive at Philly anytime from noon.

When I made my reservation it would have been nice if kayak would have included my luggage. Unaware that I had to pay $45 each way. Should have asked at reservation time if luggage was being checked

When I made my reservation it would have been nice if kayak would have included my luggage. Unaware that I had to pay $45 each way. Should have asked at reservation time if luggage was being checked

Crew was a little surly. But plane left on time and arrived early. All one can ask for. New 737 Max was nice.

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.

I used by Skymiles to upgrade to First so that I could comfortably work using my laptop. But WiFi was intermittent and unavailable for long periods. I feel like I wasted 70,000 miles :(

Great as one can be for a one connection 6 hour flight

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.

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 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

Just sat on the run way after we arrived early

Stored my cloth purse under seat in front off me as instructed. When I retrieved it, half of it was soaked, along with everything inside it. I don’t really know how that could have been prevented because the area did not look wet, but I was not happy about it.

It was easy to board, and the staff was friendly and helpful. What could have been better is that I shouldn't have to pay extra for a seat that doesn't recline.

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.

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

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.

It was a late flight; crew was invisible. Zero air flow - the tiny plane was a sauna; the left the lights on for 1/2 of the flight; there was no water. Never again.

What an amazing plane! We flew a 787 to Miami. Although the Internet was not functioning, it was a wonderful flight.

Plane was in good shape, multiple passes from the drink cart, and one of the smoothest flights I've had in a while.

After lack of help in Philadelpha made us late to board our flight to akansas City, our flight to Kansas City was very good. And the flight attendants were also very good. The only thing that sucked was problems with assistance in Philadelphia caused our bags not to arrive.

Legroom was decent, but the seat comfort was horrible; I believe the seat cushions have lost their cushion. I was uncomfortable and had back pain throughout the nearly five-hour flight. WiFi did not work despite my attempts to get it up and running. This was very frustrating as passengers all around me were streaming football games, movies, and accessing email and text messages. One flight attendant suggested it was my seat, but that makes no sense, given WiFi doesn't work that way. On another note, I rarely have a good experience with aainflight.com.

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.

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

Maximizing profits is one way to a healthy bottom line, the other is repeat business and referrals from satisfied customers. Frontier has clearly chosen the former. One of many examples: Family emergency required me to cut trip short. Headed to the airport to fly standby for the return trip I had already paid for (yes I understand prices vary with demand etc). Was told there is no standby and that I would need to pay for, despite what it's called by the company, what amounts to a new ticket. And surprise surprise, there turned out to be dozens of empty seats on that flight. To say nothing of the sleazy third and fourth party resellers, the flight/ticket insurance I elected and thought I had paid for that mysteriously wasn't there when I needed it before I left, and on and on with third world sleazy management decisions. The inflight coffee (that I had to pay for) was very good though.

Flight delayed and missed connection. Next available flight was a 10 hour delay.

Great flight, no problems. I wish they would increase the checked bag weight limit. Packing was very stressful.

I am writing to express my disappointment with my recent Frontier Airlines flight. I was charged $99 at the gate because my bag was said to be too large, yet once onboard there was no available overhead bin space, and I was required to place the bag under the seat in front of me anyway. This made the charge feel unnecessary and unfair. Additionally, before the flight even took off, I was asked to move from the seat I paid for into a middle seat so another passenger and her cat could have my seat to themselves. I was not offered compensation or an explanation for being moved from a paid seat. Between the unexpected bag fee and being forced to give up my seat, this experience fell well below acceptable customer service standards. I would appreciate a review of this situation and appropriate compensation.

Terrible. Flight cancelled with no reasoning and no flights to rebook. Employees were useless and did nothing to help. Did not even know where to retrieve luggage from the cancelled flight. Flyers beware.

sluggish boarding and arrival procedures, fake nice flight attendants, and lots of delays.

You get what you pay for nothing essentially but a hard uncomfortable seat that doesn’t recline and kids screaming all around you and chaotic boarding and limited check bag weight allowance when compared to other airlines

Not very good. Paid in excess of $400 for assigned seating for my family and that was not provided. I want that money back.

Check in at Philadelphia international was absolutely terrible! I fly 2 to 3 times a month and avoid frontier at all cost and will never fly Frontier again! The night before travel, I tried checking in however, the app was giving me an error, so I went to the desktop, which instructed you that you need to use the app. The next day I presented at the check-in gate after trying at least a half dozen times prior to getting into the airport and continuing to getting the error in the app. I actually had rebooted my phone numerous times and reinstall the app just in case. My phone is only one generation older than the current model. It has no problems completing a frontier flight purchase or any other app issues. There was only three frontier employees working at check-in and a huge line while I was in line I continued to try and check in via the app. As I approach the desk, I was dreading dealing with the agent. He was extremely unprofessional, anti-semantic & very ignorant, and mean to the people in front of me, as well as the people who ended up being behind me. He literally told people “Man I don’t care bout y’all” in his native dialect! Maintaining my composure I approached and explained the situation. To which he replied, you’re gonna have to pay then! I don’t understand. It’s an issue with their app not allowing me to check in! Not my issue! He told me if I pay cash it would be $15, $25 if I pay credit card. I don’t understand a $10 difference for paying with a credit card? I am completely cashless so I continued to try using the app to avoid the $25 fee, Which I still don’t believe that I should be responsible for since it was Frontier’s technical issue!!! I continued to check in via the app a couple more times after he verified I was doing everything right he proceeded to continue to belittle the people behind me. Yelling at them saying I don’t care about you people! I cannot believe that this is the way that businesses would treat its customers! Unfortunately, the black mail with dreadlocks did not have a name tag all he had was a frontier sweater on! For the $25 fee that I ended up getting charged on my credit card. I should’ve just booked originally with Spirit or any other carrier! I have no problem paying fees that I should be responsible for, but when it’s due to a technical failure of a company, the customer should not be responsible for it! I cannot believe that it’s not frontier going out of business!

terrible cascading delays and unhelpful customer service. uncomfortable plane. crew was great, however!
