Insights shared by verified travelers who flew to Princeton 
ElenaFlew with United AirlinesSFO-EWRJun 2025
Construction in the terminal so allow for extra time in SFO. Very easy finding luggage and getting outside at Newark. Also, this time, took the Express Bus into Manhattan - $25 is a good price, though the bus arrived 20 minutes after the scheduled time.
MathewFlew with DeltaSAN-JFKJun 2025
Make sure to pack 2-3 days of clothing in a carryon.
Verified travelerFlew with Spirit AirlinesMCO-EWRMar 2025
For budget travelers, this is a good airline. Stick to the luggage dimensions, bring a snack and a book or entertainment that does not require WiFi and you will get to you destination for a great price.
MaryannFlew with United AirlinesSFO-EWRMar 2025
Bring your own food with you. Airport and airline food is expensive and you WILL need something to eat on such a long flight.
Kent ThienFlew with Korean AirSAV-JFKFeb 2025
Try to check in online to avoid the lines
MollieFlew with Spirit AirlinesDTW-EWRFeb 2025
You have to weigh your bags yourself, there is no assistant to help check bags like on delta, so it takes longer and is more of a pain. Long lines, count on an extra few minutes. Other than that, everything was fine.
HartajFlew with United AirlinesRDU-EWRDec 2024
RDU gates can be busy. Newark airport still being upgraded, expect construction. Complex EWR layout can be difficult to navigate. Good luck! 💗
FrankFlew with Spirit AirlinesMIA-EWRJan 2025
Don’t get to the airport to early. The boarding is orderly so you don’t have to be there too soon
GregoryFlew with United AirlinesORF-EWRDec 2024
A good flight route - note that the EWR layovers are shorter than you expect. Boarding often starts earlier than printed.
JubyFlew with SouthwestATL-LGAOct 2024
Get to the airport early enough to relax and enjoy the good grub found in the airport
JoanFlew with Alaska AirlinesSEA-JFKNov 2024
SeaTac should add sand to the painted floor from the terminal to the light rail. It is VARY slippery when wet and the northwest (Seattle) is known for rain.

You get a little a Pretzel bag or Biscoff crackers. Bring your snacks for the long haul. And listen for free gate checks !

Walk with something to eat, because everything on the airport is expensive.
RolandoFlew with British AirwaysAUS-JFKJun 2024
Pay for the upgrade to be bumped up in an earlier group. Makes finding a spot for your carryon bag much easier. Also, please make sure any purse is packed into your personal bag. When they say a carryon and 1 personal item they mean it. Save yourself stress and holding others up by sticking to it.
MarkFlew with JetBlueTPA-EWRAug 2024
A rapid journey. Preload entertainment onto your mobile device beforehand. Investing in the upgrade for additional space is beneficial.
EricFlew with Spirit AirlinesMCO-EWRJul 2024
Take the early flights, especially in the summer. Save the headaches you’ll receive.

Show up early. Security line was long (admittedly at the end of the 4th of July weekend).
RobertFlew with Alaska AirlinesSFO-EWRJun 2024
Bring some food on board for the flight
Verified travelerFlew with British AirwaysMIA-JFKJun 2024
New York JFK is massive and the signage there for connecting flights is not so good as you need to travel via AirTrain between the different terminals and the signage for this is missing in some places, making it confusing as to which way to go.
WilfredoFlew with JetBlueRSW-EWRMar 2024
1. **Book Early**: Secure your tickets in advance to get better deals. 2. **Check for Deals**: Keep an eye out for promotions or discounts on flights. 3. **Pack Light**: Consider packing light to avoid extra baggage fees. 4. **Arrive Early**: Reach the airport with ample time for check-in and security. 5. **Stay Updated**: Monitor your flight status for any potential delays or changes. 6. **Comfort Items**: Bring essentials like snacks, a neck pillow, and entertainment for the flight. 7. **Stay Hydrated**: Remember to drink water during the flight to stay refreshed. 8. **Plan Transportation**: Arrange transportation from the airport in Newark to your final destination in advance.
AlexanderFlew with Spirit AirlinesORD-LGAMay 2024
Know your connection options — specially when LaGuardia Airport (LGA) only has buses going to/from the airport to the rest of the city. Luckily, the one to the subway station (Q70) is free-of-charge to ride on!
Verified travelerFlew with LufthansaRDU-EWRMar 2024
If you're connecting at Newark, you don't have to go through security again, which was a pleasant surprise.
Verified travelerFlew with Kenya AirwaysCMH-JFKMay 2024
Get to the airport early especially for International flights so as to make sure screening is completed. The Delta kiosks are glitchy and do not always work
PeggyFlew with Alaska AirlinesSEA-EWRMay 2024
Bring earbuds or head phones to watch movies on your electronic devices. The plane doesn’t have a screen for showing movies.
LuisFlew with American AirlinesPHX-JFKMay 2024
Google the airplane they will fly in to see if it will be comfortable or not. I recommend the 777-200ER

Show up extra early, especially if you are flying with kids. There are no employees around to assist you.
MagedaFlew with United AirlinesLAX-EWRFeb 2024
If you use the United mileage card, you will have priority boarding, which puts you to board in group 2, you get one free luggage checked in, gives you 2 free annual passes for United Club, drop off bags it's easy and convenient on level 2 in both airports Lax and Newark after checking in online

The flight used a B767 with a very old interior from before 2014. The entertainment system did not work at all during the flight despite attempts to reset the system. It was like they flew this route just to be competitive.

The flight used a B767 with a very old interior from before 2014. The entertainment system did not work at all during the flight despite attempts to reset the system. It was like they flew this route just to be competitive.

They changed planes and the new plane couldn’t carry enough fuel to fly across the country so we had to stop in Kansas City to refuel. Flight was delayed .

Flight was too crowded and seats are too small, especially since passengrs are getting larger. Having a middle seat is ALWAYS tough! Woman on my left was large & kept creeping in to my space. Flight personnel were great! Have more savory rather than sweet snacks please.

Flight was crowded and the woman sitting on my left was large & kept crouching in to my space. You need bigger seats or smaller passengers to fit into the seats you DO have! Snack were OK. Would appreciate if airlines had more savory rather than sweet snacks, thank you!

Delayed flight (1hour) plus a long layover after an overnight flight with no backup plane available.

We were delayed, which I think had to do with air traffic control. Otherwise, everything was great.

The boarding process needs to be refined. Sometimes the gate crew calls out the zones and then flip to showing the.zones boarding on the gate monitor display. So, unless you are huddled around the gate lanes watching the monitor, you could miss your boarding zone. Suggest the zones be announced each time a new zone is allowed to board.

The boarding process needs to be refined. Sometimes the gate crew call out the boarding zone, and then flip to the monitor to show which zones are boarding. So unless everyone is gathered around to see the monitor there is usually confusion as wi which zones are boarding.

On time flight. Seat comfort could be better in the Comfort section.

My issue was with TSA agents for delta airlines. My luggage got flagged. The agent was going thru another persons first. He took 20 min to go thru hers. I asked them to bring mine closer so I could sit down . They said you can go sit it will be fine. I said I am supposed to keep my eyes on my bags at all times. The agent was meticulously unwrapping 2 gifts that the lady had and then tried to re warp it. He was trying to be kind i get it but 20 min for me to stand watching him do that was ridiculous. It was 6 am and there were a ton of travelers. Mine was flagged for some air packed tea that I bought in Turkey. My previous delta flight and 2 others before didn’t flag it. Consistency would be nice. Also on the flight the window shades were down for take off and landing - I thought that was very odd I thought they had to remain open for take off and landing.

During booking, I kept trying submitting my payment from the Mexican website and it didn't work. After I had the idea to change it to the Canadian website, it worked but I had to be charged the equivalent of 50 CAD more. I received the clear instruction that I would only be able to check-in at the airport and that it was impossible to select a seat 24 hours before departure, that I had to pay 144 CAD to do so, although not only was I able to check-in 24 hours before departure, but I could have selected my seats for free then. All in all, I almost threw $200 out the window due to misleading information. Besides, the app kept crashing, the information to get to the gate on the app was inaccurate, my gate was switched and I was only informed once in the air (luckily I had noticed the departure pannel), I was not addressed in my language beforehand and even if I tried I was immediately answered in English (which meant the crew understood but didn't want to answer accordingly), there was only one snack & beverage service on my medium haul flight and no beverage service on my short haul flight. To be fair, the planes were comfortable, the crew apart from the language issue was helpful, dynamic and engaging, the plane was clean and the directions were clear and direct. United has a lot of potential to be one of my favourite airlines, but the devil is in the details and a lot of them missed the target.

The worst landing I have ever had on a domestic flight. Thought we would lose the landing gear on landing in Newark. Then we spent 40 minutes trying to position the plane in the right place to be able to get the jet way to the plane. The plane arrived stopped. The announcer was that we were there. Everybody got up, then we were told to sit back down because they had to have us towed to a different position. We got towed and then everyone stood up and they told us we were in the wrong position to sit back down again, and then we got towed to a different position This did not happen immediately. It was 30 minutes while we wandered around a small section of the tarmac in Newark close to the gate, but apparently not close enough. Horrifying experience The CAB should be investigating that flight

Boarding was organized. Plane seats comfortable and service was attentive. Food options were good.

This was a very average flight. The seat was out of alignment so more uncomfortable than usual. The cabin felt not well maintained. But I safely got where I needed to go.

Flight is clean and ontime. Crew is friendly. Snack can be better and the internet connection is poor

All of the United employees I interacted with were professional and courteous. The aircraft was clean, the food on the flight was good. No complaints here.

There was no food available for this red eye... one little waffle cookie for a 6+ hour flight... thank God I was able to sleep some

Terrible. Delayed 7 hours, and cancelled the flight, leaving me stranded and out of pocket $500 for an alternative last minute flight

Not a great experience. We paid for the upgrade for premium economy seats and seated ourselves in very comfortable seats. Someone came along with the same seat on their boarding pass. The aircraft had been changed and as a result we were booted out and sent further back to small uncomfortable seats. After complaining we were moved to emergency row seats, which gave us more leg room but the seats don’t recline. For people in our 70’s we found having to sit upright from California to NJ very uncomfortable. Not sure why they chose to move senior citizens instead of the two people that were allowed to take the more comfortable seats. Not happy.

Cramped seat even in economy plus seat 10A. Over booked flight, no space for the bags

Typically flights with AA are good. The staff are pleasant, welcoming, and efficient.

A couple ladies from the crew were so rude and nasty. Thought they were mad at having to be there especially if you asked a question. This will make me think twice next time if I book a flight with you.

Delays to take off and to leave the plane after landing added a lot of time to this flight.

Poor seat in rear of aircraft Food at Admiral’s Club Terminal D at DFW inedible

Always seated jammed in rear of aircraft Admirals Club food at DFW terminal D was absolute worst food experience and I pay $600/year to eat this dried out junk

Flight was delayed because of a bird strike. They had another plane available within 45 minutes.

Mostly good. Flight was crowded but Airline personnel were very friendly & accommodating. It would be good to have savory snacks rather than just sweet Biscoff cookies.

It was a typical flight. We had a delay which seems to be the normality now. And we had no in flight service due to conditions.

Flight attendants on this flight were very attentive and friendly

After we landed we sat on the tarmac for 1.5 hours waiting to get to our gate. Ridiculous.

Four plus hour flight delay in New York caused us to take off after 11:30pm. We didn’t arrive at our hotel until five hours after check in. Started the trip off feeling exhausted.

Plane was in bad shape. TV’s and WiFi didn’t work. Plane need a refresh. Not enough room for bags.

Everything was great. I liked the text updates so that I never miss a gate change & I have all the latest info.

I don’t usually fly budget airlines or airlines in the United States. It was as good as any other airline. The seats are comfortable and the airline attendants are not rude & surly. Very nice flight (s).

They have the most inexperienced / rude flight staff I’ve encountered

very difficult boarding process - aggressive passengers not the friendliest crew

WiFi was not eorkig (again) And the plane was from 1990 with the screens which were.not touch and most didn’t even work and if lucky could tune in tv

I paid extra for a seat closer to the front. The TV didn’t work at all for the entire flight. Would have been nice to know before I purchased an “upgraded “ seat

It was great. I had never flown on JetBlue before, but would be very happy to fly with them in the future.

Worst flight experience ever flights canceled. JetBlue told us just did not even bother standing in line to come back in one and a half hours then without any information we had to go pick up all of our luggage and spend over $2000 in accommodation just to get home. JetBlue said that the next flight available for us to get home would be three days later. Absolutely absurd hasn’t offered to give us any compensation do not fly JetBlue horrible company. They said it was based on the weather and the weather is great in all locations that we would’ve been flying to total hoax. I think it’s a conspiracy theory.

Changing the flight time to 6:15 am on the return flight is extremely inconvenient. The flight was okay. It was on time. The crew was friendly. The seats were uncomfortable. All the upsells are annoying, and I would prefer paying a single higher fee and not have to purchase so much extra.

The terminal crew is so rude cabin crew is extremely rude flight is very good

The incoming plane ✈️ was delayed 5 hours en route to Raleigh. My flight was delayed for 5 hours 😢. Finally boarded and then de boarded due to an AC problem. A very tough and long night.

The flight was 3.5 hrs delayed. I was not notified prior to arriving to the airport via spirit app. or via boarding pass that I already had loaded on my phone. The agent that i saw at the counter didn’t mention anything about the delay either. I only saw the update after logging in to my email account.

Although our flight had delays due to three different reasons, it was good. Staff continued to update us which made every one comfortable. We felt the captain and crew had our safety in mind the entire time and no one seemed to lose their patience.

Unfortunately, spirits crew had us boarding and parking the plane often, would wait long periods of time before allowing the people attending the flight on the plane to know what was going on this caused for my plane to not only get diverted but then canceled at an airport 2 hours away and basically stranded with charter buses MAYBE being hired. I was left with no choice but to stay overnight and use a comp room in Altantic City to then arrive home the next day. This trip was the first time seeing my partner since he joined the Air Force and this stressful ride caused unwarranted tears on what was supposed to be an east flight home. I understand weather is unpredictable but to have passengers deboard to then reboard an hour later to taxi on the runway for another hour to then basically leave an entire fight stranded. I waited almost 30 minutes at the airport and not one employee could tell me about a charter bus so I had to leave and make accommodations to stay overnight and get a ride home.

This was the first time I use Spirit Airlines and was pleasantly surprised. It was a last-minute booking and I was happy to see there was availability on your airline for a price that was affordable. The staff was friendly. The only things I thought were missing, were the ability to recline the seats, although I don’t use that very often, and it would’ve been nice to have power access at the seats to plug in my devices.

The flight was canceled and was bounced around time wise with my elderly parents. That being said the gentleman in custody service was amazingly helpful

It amaze me how other airlines leave on time and Spirit always have some type of delay. I’ve flown with Spirit many times, but it reached a point I’d rather pay twice the amount and not deal with this corporation they never do nothing to reimburse people for their time or headaches.

Too many time late and postponed No electrical power for my electric devices
