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

Insights shared by verified travelers who flew to New Castle 
LisaFlew with Delta-Apr 2026
I wish I knew the deal to get uber/lyft in advance and if I should book while on plane or at baggage claim. I waiting’s about 10 minutes which I could have avoided had I known
Verified travelerFlew with Qatar Airways-Jan 2026
Our flight to Philadelphia was full and the gate announced that there would probably be a full state for carry-on luggage at Zone 5 of boarding. In reality, they announced that the overhead bins were full after Zone 4 had boarded. Passengers need to be prepared.
LouesaFlew with American Airlines-Jan 2026
The airport is large so allow plenty of time even if you have TSA pre-check.
JacquelineFlew with American Airlines-Jun 2025
Get familiar with navigating the Portland airport. It’s been four years since I was there last visiting family and I believe the airport’s been refurbished and enlarged, etc. but it’s very nice.
CHARLESFlew with American Airlines-Mar 2025
There are no food or vendor services in the boarding areas of Terminal 4 at LAX.
Verified travelerFlew with American Airlines-Sep 2024
Do not check in your docs, and medication in a check bag. Carry with you to the cabin.
CHARLESFlew with American Airlines-Mar 2024
Make use of the food, beverages, and amenities in American Admirals Club in PHX before departure on any flight.
ElaineFlew with Alaska Airlines-May 2024
If you have any metal in your body (e.g., spinal fusion screws) make sure you get in the line for the TSA security screening booth that makes you stand on the yellow marks with your arms over your head. I wish I had known this before I wasted time in the alternate line with the walk-through detector.
Verified travelerFlew with Frontier-Mar 2024
Watch out for “fake Uber drivers” know who’s coming for you
Verified travelerFlew with Spirit Airlines-Jan 2024
I didn’t realize that we had to take a train from check in in order to get to the gate. That took a lot of extra time.

Airline reviews

Seated at front bulkhead for a smidge extra leg room away from home and on flight back home. Away crew was very proactive about assuring our carryons had space close behind us (because no seat in front of us our personal items had to be in a small bin overhead). They actively required passengers place overhead luggage on its side so more items could fit in bins. Home crew made no such efforts. I had to struggle back rows to get overhead bags upon landing, no crew help then either, and some disgruntled passengers as I and others retrieved our bags. There was a system that worked pretty well. The home bound crew just didn't feel like working.

Southwest has inacted unfriendly customer policies like other airlines. Watch the fine print very carefully if you are having to alter flight arrangements. Rules are now complicated and very stilted to travelers sacrificing travel funds (unlike before where the simple, straight forward flight change policy was worth the extra premium for ticket price.) On the positive side, SW Flight crews are still wonderfully helpful.

Flight left on time and was early landing. Seats not comfortable and not enough space…

Flight left on time. Seat spacing is way too small…

It would have been better if the flight was on time

Fairly good - the seats seemed more comfortable on this flight. The staff out of Detroit were quite friendly. But they directed us to the wrong carousel for luggage. :(

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.

I liked the new boarding process. I thought the buyup options (legroom, early boarding) to be easy to request and reasonably priced. All the Southwest team from gate to in-flight were so nice.

Flight time kept changing and so did the gate. It was very frustrating

Exceptional. The gate crew responded quickly and got me onto this earlier flight as the final passenger, saving me more than four hours of wait time for my reserved flight.

Terrible - the flight was delayed taking off after boarding. Then the flight circled lga before landing. Significant delay

The actual flight was smooth and we arrived earlier than expected which was great. The flight attendants gave unclear instructions and were rude. They seemed overwhelmed or flustered for the flight. Inflight service was delayed and unsure why.

Everything went smooth from check in, thru TSA, then boarding, and a smooth flight to ATL.

There were weather issues in the area apparently; however, that was not obvious from what we saw outside of LaGuardia. We were delayed leaving (which I understand); however, once we were on the plane we didn't leave for a long time. It may have been two hours?? - all I know is that we sat there for a long time with no information as to why we were not taking off. Finally, after 45 minutes to an hour (maybe?), the pilot gave us an update that no planes were able to go in the our flight path direction (or something like that) due to weather. There was nothing additional added. What does this mean? Why is this? What are the options? When will you give us another update? There were no updates for maybe another 30-45 minutes. There was no explanation as to why we couldn't be rerouted to avoid the weather. We had no information at all. We just sat on the plane (for about 2 hours) with very limited information. All I would have wanted is an explanation as to what was going on. Tell me there is bad weather coming our way. Tell me they are working to reroute us around it (which is what they did). Tell me SOMETHING.

My 4pm flight did not leave until about 10pm. I did not enjoy this experience.

I had an extensive delay on my previous flight and we had another delay due to the crew not being there. We were scheduled to have a late arrival but due to the delay it was even longer.

Had one of the worst travel experiences I've ever had. 1.5-hour delay turned into being held on the tarmac and our pilots timing out. Was supposed to take off at 4pm and didn't take off until 10:30pm.

Delayed 7 hours Crew and employees were nice Extra long flight but at least we got in

The flight was delayed at the very last minute and no information, both of my round trip flights were delayed at least the BNA to Boston was informed earlier but the return one was horrible

Nothing really it’s just the flight availability that hurts sometimes

I missed the flight due to maintenance issues. This is the second flight I’ve missed in four days because United allows such little time between layovers. Very disappointing

My return flight to Honolulu (UA 1170) was on a 777-200. I’d forgotten the weird seating arrangement in first-class (2-2-2); I was in 1B, so I faced the passenger in 1C. Unfortunately, there was a problem with the flight computer, so we left LA an hour late (6:05pm). The meal I chose was Korean BBQ Glazed short rib. It was served with a nice salad and fried rice. This meal was better than breakfast on the outgoing leg. All in all, a decent flying experience. Ratings: 777: 3.75, food: 3.5, service: 5 (out of 5).

Food was not Good Nuts came very wet & not tasting Good Main course I asked for Steak they got me Chicken because they don’t have more !!!!

It cancelled and we were unable to catch our connecting international flights.

Terrible service - they don’t want to be there and bad food. Entertainment system in economy from the 2000s

I did bought anything… I don’t understand how this book appears to me . Ridiculous

Leaving at 7 when scheduled to leave at 4:20 - you tell me. Understood there was a ground stop. Then having to "reboot" the plane because of a lighting strike, also understood. But basically the flight was a "clusterf#$%".

No drink service but there was no N/A as an option to choose. Seats were extremely tight. I am under 5.5 and I bumped my knees have no idea how taller people could manage.

My flight from Honolulu (UA 1221) was on a very old 757, no video monitors anywhere. If you wanted to watch a movie, you needed to do so using the United app on one’s phone. WiFi was $8 for Mileage Plus members; I demurred, choosing to spend my time reading a novel using the Kindle app on my Samsung S26. The meal was okay … Breakfast on any domestic airline is so-so as a rule and this one was no exception. The best part of the meal was the fruit plate and the warm croissant. The highlight: The flight left on time and arrived early.

Flight delayed, last seat on the plane, no arrival Gate available due to the plane departing late

Nothing was good about this flight. Although the flight actually departed more than 3 hours late, due to “air traffic control management” we pushed back from gate 2 hours and 20 minutes late and proceeded to sit 100 yards from gate for and then n tarmac for another 1/2 hour additional 20 minutes

Our flight was delayed to Louisville. What made this worse was they did not have another flight attendant to service the flight. This caused an even longer delay. Then when a flight attendant did show up, she chose to "swap" flights with another flight attendant. Therefore, we had to wait longer for the other flight attendant to come to our flight. This is information that the gate attendant should not have shared. Processes and execution at American are broken. Passengers are feeling it. Fixing this starts at the top of the organization.

Both the gate agent and flight crew did a horrible job of expediting the boarding process. It was simply miss managed. The airplane was late to Tampa. Therefore, they should have expedited the de-boarding process and also boarding process. This did not happen and caused me to miss my connection. I ended up with a 7 hour hour layover just to get home. The overall flying experience on American has simply been degraded. On-time performance is a real problem every single week. This has caused me to consider moving my loyalty to an airline that has better performance metrics.

One thing you can always count on is your AA flight getting delayed. This is not surprising when they operate these planes like a greyhound bus with wings.

Mostly excellent. However, many too many gate changes. Connecting flight at ORD changed gate 6 times.

It was my first time flying with Alaska Airlines and it was a pleasure!

DFW notification of changing the gate notice was an inconvenience.

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.

Very long delay at PHL. The old section of terminal F is a disgrace. Take-off was 3.5 hrs late. It was not just the bad weather, but also too many jets occupying too few slots, a very PHL-based problem.,

Aa cancelled my flight where I was in first class seat 4B. They auto rebooked me on another flight, did not give me a seat assignment until at the gate. Where I got seat 29f, for a 4 hr flight. No accommodation at all for my first class ticket. Left 3 hrs late as well.

Sat in the airport waiting for my flight for 5 hours. Finally got on the plane only to be thrown off and told that my flight was cancelled. Zero customer service. Nobody spoke to us. Just the worst

When I was boarding my departure from Raleigh to Orlando I was inappropriately scolded by a female dog named Mia because I didn’t pay in advance for my carry on bag ($75). Frontiers website is confusing regarding pre-paying for carryons so it was a simple mistake. I also had paid for “upfront plus” meaning me and my son were seated in the front row with no one in the middle seat ($450 upgrade). When we were boarding Mia said “sir, you didn’t pay for your carryon” in a not so polite tone and told me to get out of line and come back to the counter to pay for my carryon. The way they had the retractable rope left me no room to circle back without making the people behind me move so I just stood there and then she said a second time “sir!! Go pay for your carryon” in an embarrassing tone. I then moved their rope so I could get back to the counter when a second female dog then asked “are you done!?!?” because I had said “do you want me to bulldoze the people behind me?” I then said you do realize I paid over $400 for upfront plus so I was certainly not trying to sneak a carryon bag without paying. Long story short, I am soooo done with discount airlines!!! By the time you pay for all the “extras” you might as well have paid for Delta Southwest or American! Frontier airlines sucks and I was embarrassed by a female dog named Mia!!!

Frontier is good until they cancel your flight. Way too many cancellations.

I know Frontier is a “no-frills” airline. I understand the concept. However, I jumped on some tickets for our family vacation, expecting to play a bit of a game to figure out the family bags and not over spend. In the end, I got the short end of this deal by far. 1. I did not expect them to charge the baggage fee for each direction. It makes the fee look high-ish at a glance, but reasonable. Then when you get to checkout and realize you have to pay it twice to come home with your luggage, it becomes ridiculous. 2. The low checked bag weight limit. I am used to packing a 50lb bag with my preferred airline. Frontier’s artificially low 40lb limit more quickly triggers the extra weight fee, which almost DOUBLES the price of the bag if you go over ($79 for the bag/$75 for the next 10 lbs) 3. The fee for a carry-on bag is the same as a checked bag but with a lower size and weight limit. Make it make sense! 4. The seats are terrible. My 2.5 hour flight almost had me losing my mind. I’m 6’3” and my femurs barely fit in the space provided. My knees had to wiggle just right to jam into the crack next to the armrest of the seat in front of me. The cushioning was thin and inadequate. I am tall but I’m not a freak. These seats are unacceptable. 5. I overheard the woman next to me speaking with the gate agent about being charged a $25 fee for not checking in online - she checked in at the airport counter when she arrived. That’s ridiculous. She was old and in a wheelchair. She had a paper boarding pass, and was obviously not tech savvy. She should not be punished for that. 6. They do not have good placement in the terminals. It was always out on the end or down on a subfloor, and we had to walk out on the tarmac almost every time. In Denver. Their home airport! 7. Every time I loaded a new page on the website while buying my tickets or my bags, it was constantly trying to upsell me on some esoteric bundle. Like, a pop-up every time. Very annoying. 8. No screens in the boarding area (at least where we were) to confirm you’re in the right place. Just static gate number signs. I am sure these are standard practices for Frontier, and I should have read more about them before I purchased tickets, but as a result of this single round trip, I do not plan to ever use this cut-rate airline again. I would rather pay the normal amount for a ticket and be treated like a customer instead of a mark.

Our flight was delayed 2 hours and when they changed the the time to 1 hour I wasn't alerted and when I checked the gate the plane was still there but they already shut the doors so I had to buy another flight.

Great except upon arrival it took them a long time to open the doors

Frontier feels like a family I Worked for Eastern Airlines back in the day and I felt the family vibe that I had then. Thank you

Terrible. Delayed my family flight for several hours affecting family plans

Tiny seats, no entertainment, no amenities, delays, they charge for carry on and their allowed personal item is smaller than in other airlines.

The seats are tiny and they don’t recline. The planes are dirty and very small. You have to pay for carry on and even the personal item that you’re allowed is smaller than with other airlines. Flights are usually delayed and there’s no screens or any amenities or entertainment.
