Flights from Allentown to the United States: the best tips from KAYAK users

Avoid Charlotte. The mountain weather is so unpredictable, plus the poor recent airline scheduling services, you will be stranded in the mountain with small airport, with limited alternative transportation methods. The airlines had been delaying the flights and stringing you for a few hours, then cancelling your flights and simply letting you re-schedule your own next legs with the existing flights, which may or may not take off. Airlines have not been courteous enough to schedule more flights to accommodate the canceled ones. If you cannot avoid Charlotte, be prepared to be stranded for extra 1-2 days before you can get out to your final destination.

The cabin and bathroom experience was poor as the cabin and bathroom were dirty and showed signs of an older plane that had not been updated for Customer’s, comfort and health. There was gum on my seat when I arrived and dirt spots around the fan and light controls. The flight was almost entirely full, so there was no way I could be moved from my seat. Th bathroom had the peeling paint.

Wifi worked inconsistently; outlet to charge computer did not work.

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

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.

The only downside was my cell phone charger wouldn’t work in the charging port but everyone else’s would work in them all. My cell phone cable works fine in my hotel room in Frankfurt.

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.

Smoothly flight, pleasant flight attendants. I wish there were better food choices.

Surprisingly easy! I was hesitant to try this, but the cost swayed me. I actually felt like I had less stress than all the taxiing and possible delays that occur with short regional flights where you spend less time in the air than getting to and from the plane..

Terrible. We needed to change return flights due to an incoming hurricane. They would not refund our return flight.

The employees at Sioux Falls airport were friendly and helpful. As a veteran/retired military Allegiant allows two checked bags, one carry on bag and a seat on the plane all at no cost. The flight crew and pilots were friendly and very competent.

The check-in and flight crew employees are excellent. The flight was good and the seats were adequate.

The flights to and from Cincinnati were great at being on time for both, departures and arrivals. The planes could use some updating.

It was a dismal experience. The flight was delayed for 4 hours, and we spent hours in the plane, without air, during the summer. We were not provided with water, and the medical assistance was inadequate when it arose.

The landing the pilot was very smooth. The flight attendant was kind of rude.The boarding the plane in punta Gorda was not great made us wait out in the heat 😞

My exit seat was very comfortable Coffee was to be purchased but sodas free 😏

Check in on the web portal was cumbersome! After several attempts I finally got the boarding pass.

My TSA number was missing from my ticket which shouldn’t have happened since it’s in my file. The on board flight attendant who was a male, did not want to help me put my luggage in the overhead bin and made a very rude comment and was very unpleasant. The good… the woman who fixed my ticket with the TSA number was excellent and I had extra legroom which was perfect.

Plane had mechanic problem that was never explained. Had to bring a plane from another airport. Six hour delay. No apology for the delay. Not even an acknowledgment.

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

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.

The airline schedule services was simply mediocre. The ground crew is fine; they are doing their best. The after-delay services were simply poor, and after-cancelling services were almost non-existence. Receiving refund is one rescuing point, but please keep in mind that, people wants to get home or get to their destinations. Cancelling without aftermath recourse is simply poor services. AA needs to fire the marketing department, and the customer-service related leaders.

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!

Booked direct in July '24. Turned into a 14 hr layover (both ways) in Denver. My 5 day vaca turned into a 1 day . Not good, BUT,... Thank you for the people @ Frontier who were professionally friendly & approachable.

25 dollars to get a boarding pass abusive nasty folks at the boarding pass check-in desk flight delayed abusive nasty personnel at gate no one knew what they were doing at boarding a real cluster fbk I took a different flight back frontier socks

$80 fee for a backpack as a personal item is robbery.
