Flights to Princeton: the best tips from KAYAK users' own experiences

Insights shared by verified travellers who flew to Princeton 
Verified travelerFlew with British AirwaysLHR-EWRMay 2025
Gate assignments are made shortly before boarding and each letter dedicated terminal group is separated by a long walk or a crowded rail ride. The metro ride between the terminals and the city can be complicated if you go in with no research. We consider ourselves capable people but Londons rail system is a mess to get a grasp of.
Verified travelerFlew with British AirwaysLHR-JFKJan 2025
Prepare for the unexpected. It’s a long flight and anything can happen. Have some snacks and drinks with you. And other emergency items you may need.
786ottoFlew with FinnairLHR-JFKSept 2024
If you have tight connection and previous flight is late , don't panic they will wait for you if you have connecting flight with same airline.
KennethFlew with IberiaLHR-EWROct 2024
Heathrow is a large busy airport that requires a lot of walking.
Verified travelerFlew with British AirwaysLHR-JFKAug 2024
People have to make sure they have plenty of time (2 hours minimum) if they need to change terminals. Heathrow is a monster airport, it's giant, so if you want to shop or eat or just look around, you need more than 2 hours between flights. Otherwise, it's great, the security was fast but thorough. I loved that I did not have to remove my shoes and the employees were patient and polite, not like at JFK. The shuttle buses are annoying, but at a huge airport like Heathrow, it's a must. The drivers of the shuttles are crazy, they don't care if people are falling down or not, they drive aggressively. However, people cannot fall down because the buses are packed to the gills. So, instead of shuttles, a looping airtrain would be a much more convenient and probably faster way of connecting the terminals, just like at JFK. The frequent flights between London and New York are much appreciated.
AntonellaFlew with IberiaLHR-EWRJul 2024
London makes you take out every single toiletry even below 100ml and if they don’t all fit in one tiny bag, they make you throw it away. Check everything in your checked luggage!
Juan LuisFlew with DeltaLHR-JFKApr 2024
- Enter as much information as possible using the Delta or Virgin Atlantic app. - Confirm which is the Terminal of your departure. - Arrive three hours early at the airport.
Verified travelerFlew with British AirwaysLHR-EWRFeb 2024
Even if you have a long layover, be prepared to travel a long distance to your gate once it gets announced. Do not delay in heading to the gate. Be prepared for a very crowded airport experience.

Over 1 Hr delay. No APU so no AC on ground. Plane was hot during boarding and then they closed the doors over 20 minutes before engine start so interior of plane was steamy hot and stuffy. Could have been helped by opening doors until ready to depart.

Over 1 Hr delay. No APU so no AC on ground. Plane was hot during boarding and then they closed the doors over 20 minutes before engine start so interior of plane was steamy hot and stuffy. Could have been helped by opening doors until ready to depart.

Ad experience - been flying many years with them but they are losing out to other carriers with their service and bagage / seating policy. My 2 12-yo kids were not placed with the parent. Absurdity.

Short flight so it was okay. Nice crew, all very pleasant and professional. We were near the back in row 27 so just as we got our drinks, we started our descent so had to drink very quickly!

KLM remains a quality flag carrier airline which maintains its standards whilst all their competitors are lowering theirs.

Our first flight was delayed so we missed our connecting flight. However it was easy to book a later flight on their app.

My flight was delayed by 6 hours then I missed BOTH of my connecting flights, I then had to stay in the AIRPORT at JFK because soooooo many people also suffered from missing flights and there was no hotels available. I would like to be compensated for this experience! I had to stay in the airport for over 16 hours!

Klm start boarding while somw air issue in the plan

The service was great. However the lounge only gets passing grade

Cabin crew professional, polite and friendly, boarding was seemless, but come on KLM surely you can do better than a pack of cheesy biscuits as an inflight snack

Cabin crew were excellent, very proffesional, polite and friendly, in flight snack was underwhelming, a packet of cheese biscuits, im sure KLM could run to a sandwich!

Food was the worst I’ve had on a VA flight. Normally it’s a lot better

I was my pleasure to fly virgin on my birthday for my first solo trip ever 🫶🏼

These are one of the older seat arrangements facing away from the windows! Not particularly convenient sets. No storage spaces. NO COAT HANGING HOOKS. Inconvenient business class seat compared to any other airlines of similar class. Staff are excellent! Extremely professional, friendly. Food is good too.

Overall, flight was excellent but check in was very slow for Premium Economy. Economy queue was shorter but we weren't allowed to use it.

The staff was not very polite but the flight was very very nice and comfortable and the entertainment was great

Great crew - old style upper class seats on the older fleet now feels dated

Premium economy more comfortable than economy, but not by much. Did was awful, do not try the omelette. Flight crew were helpful. Flight was delayed by over an hour. Overall but bad, arrived safely and thank God.

Food was excellent. Service was very good. Staff was very helpful to all passengers.

The crew was excellent as ever on Virgin. The special meal was poor unfortunately. More significantly when we arrived at Manchester Airport there was no air bridge provided and we had to exit the plane down a rickety stair case. This is unacceptable for a transatlantic flight. Whilst I understand that this is the airport’s fault at the end of the day the airline is responsible for our transportation and needs to do something.

Super friendly and helpful staff, from check-in desk to cabin crew.

The flight from Cincinnati to Philadelphia was satisfactory and uneventful.

All of my Aer Lingus flights were delayed. The seat I purchased with extra leg room was exactly the same as my previous seat that was free. I would appreciate my money back.

It was fine. Not worth the premium price. Overhead bins were so high I could barely reach and no crew offered to help me. Average food. Lounge in Dublin - 51st and green- absolutely appalling. Plagued with hordes of flies, dirty, meager food and beverages. Shameful.

Dear Aer Lingus Customer Care, I am writing to formally raise a complaint regarding my recent experience on Aer Lingus flight EI53 from Dublin to Seattle on 22/08/2025. Both my wife and I were seated in 15D, 15E directly under a faulty air conditioning unit. Even though the unit was switched off, cold air continued seeping through the sides and blew directly onto us for the entire duration of the flight (over 9 hours). We reported the issue to the cabin crew, but the only attempted solution was placing a piece of food-packaging sticker over the vent. Unsurprisingly, this had no effect. When we pressed further, the crew told us: “It is hard to fix it because we don’t have an engineer on board.” As a result, my wife and I remained exposed to constant cold airflow for the whole flight, and both of us became unwell afterwards, experiencing chills, sore throat and fever at the end of the flight. This has caused significant distress, disrupted our work plans. This experience highlights both a serious maintenance issue and a lack of adequate care for passengers. We therefore request: A full investigation into the defective AC system on this aircraft. An explanation of why no effective remedy (such as reseating us) was provided. Compensation for the illness and disruption caused to both myself and my wife. We ask for a full written response within 28 days. Should this matter not be satisfactorily resolved, we are prepared to escalate the complaint to the Irish Aviation Authority and Commission for Aviation Regulation and other relevant authorities. Thank you for your urgent attention to this matter. Sincerely, Temuujin Tuvshingal Myagmarsuren Ganbold

Best travel day I've had in a long time. Everything went perfectly, no delays. 10 out of 10

Not JetBlue's fault but Aer Lingus never explained how to transfer to JetBlue.

Poor check-in experience in Manchester. Delayed boarding and check-in agent never explained how to transfer in NYC to JetBlue.

We had a long delay leaving IOM. No food or drunk service as it is a short flight. Shuttled by bus from terminal to plane with packed in conditions on bus.

The space between seats was reduced even further. Could not even open the tray table fully and got compressed the moment the front guy reclined. For a long haul flight it was extremely uncomfortable.

The space between seats has reduced even further making it extremely uncomfortable. Couldn't even open the tray table properly or got compressed the moment the front guy reclined.

We did not even get on this flight as the plane never left London. I missed the email that was sent mid morning USA time, so we were not aware the flight was cancelled. There was absolutely no help from the staff at the Norse check in gates, we were told to take a picture of the board they were holding up, to try and claim our money back. We were told to book our own flights to London which ended up costing $10000 due to the last minute. And now we have to return to Miami in 2 weeks. I am not holding my breath about getting on board for that flight either.

Great experience. The flight was smooth with very little turbulence. We were in premium classic, so lots of leg room.

Didn’t know you had to pay for earbuds and food on flight. Sounds awesome and better way to not waste food or items. Comfort of flight is was amazing other than that

Unexpectedly was surprised with the space on flight in economy and the price.

I was not expecting having to pay for headphones, water and basic food in a 9 hours flight. Price for this flight was as high as any other, still I had to pay 4 lbs for a can of sprite. On top of that flight attendance gave a bothered look when I asked her for some ice for my soda. She reluctantly when to get it, brought me literally 3 cubes and walked away without looking at me to avoid another request. I couldn’t believe it. She was soooo rude. I will never book on Norse again and I will let everyone I know about this. Unforgivable, very bad customer service.

Great crew. Customer support is pretty much non existent. I had 2 tickets that were not used, the flight was overbooked. I think I should have been reimbursed for the unused tickets.

The movies were super old. The crew did not offer WATER???? 5 hours os flight and did not get WATER? Norse is the worst company I ever used and never will use again.

Why call us to board if we’re going to be made to stand in the tunnel for 20 minutes. Really hard for people with little children. Plus it took me ages to check in because my seat in Premium was overbooked so I didn’t actually have a seat. I did end up receiving my seat in Premium but there was a lot of stress and confusion beforehand. Hope is it possible to overbook seats? Especially in Premium!

We flew one way from Gatwick, London to JFK NY For 2 people $1200 and no food offered not even water. You had to buy food. Norse advertises as a low fare transatlantic airline, they may want rethink that. Crew, flight was fine. Ironically we flew American from JFK to Heathrow for $1000 (2people) and included food and drinks.

Longest check in line I have ever seen- brutal and airline personnel hustled me about the size of my bag even though I showed them that it measured exactly to the measurements posted on their site. Just super annoying- I get it - it’s a budget airline and you get what you pay for. Most of the flight were young people who seemed to have never experienced international travel. It’s worth paying for a seat otherwise you will be uncomfortable.

what would have been better would have been that my booking not been canceled by the system and had I been informed that the booking had been cancelled by the system I could have immediately rebooked and not found out that there was an issue when I was told by the system that I needed to book in. It would have also been good if either the booking agent or BA or anyone been in anyway useful. In the end I had to rebook a flight at an additional cost of $350. So no I'm not impressed by BA any of the other parties involved.

Boarding was poor. Why are first class passengers not boarded first?! Bus to the plane and then held on a packed bus because we were waiting for people on the bus before to finish boarding. Seat belt on the fist clas seat is very uncomfortable, cutting into your neck. Other than that crew, seating and food were all excellent. Entertainment, as usual - rubbish.

Flight was delayed but my previous flight was as well so It worked to my advantage. This was my first time in first class. I don't think they ever stopped feeding us. The seating area was very spacious and comfortable. The attendants were wonderful, warm, friendly and very personable.

We had a pretty good experience. Enjoyed both the flights. Crew was very good and helpful.

They issued seat assignments and sat my 2 year-old in the row behind me, separate from me and my daughter. Communication/ customer service was terrible. They told me to change it in London, then in London, they told me to talk to the cabin crew, then a supervisor came and stuck us in the back of the plane when we were supposed to be in row 25. Overall, they need to really work on their customer service. Additionally the food was terrible and they ran out of meals and didn’t have any kid options. To top it off there was no in-flight entertainment for the first hour of the trip.

We missed the connection because we had to wait for a shuttle from the plane to the Terminal. Also, we needed assistance and none was available.

When we arrived at the airport - 1st step - printing out your boarding pass - no issue. Not long lines as these machines. 2nd step - processing your bag drop off. There was only one associate there to help 10 kiosks. We had a family in front of us for 20 minutes trying to work on the machine and figure out every step for 4 pieces of luggage. My husband alerted the associate who was able to assist the family. Highly suggest that there are more associates to assist in this process. Besides this issue, security check went very quickly. Our flight was direct to Philadelphia. We had to carry our bags down two flights of steps, then out to the tarmac to a bus, then carry our bags up two flights of stairs to the plane. No one on the flight was expecting that long trek. I could see some people were struggling a bit. All in all - great flight crew, plane was clean and food was great!

There were no gluten-free vegan options available, so food was very limited on this flight, and some of the crew weren’t especially helpful about it. To make matters worse, a passenger was sick on board, and although the area was cleaned, the smell lingered for the rest of the journey. On top of that, we ended up circling for an extra hour, which only made the unpleasant situation drag on even longer.

Checking in prior on line and wait time at Gatwick was terrible. I would rate a big fat ZERO.

I checked in to bags, one arrived one was delayed. I did not receive the bag for 4 days - arrived on Tuesday, received bag on Saturday!
