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

Insights shared by verified travelers who flew to Portsmouth 
ChipFlew with Cape Air-Sep 2026
Since we live on an island, we try to arrange for a Plan B when making travel plans. There are two ways to ‘escape’: ferry or flight. The available flights on Cape Air, Jet Blue and United are scant, so plan accordingly.
MitchellFlew with American Airlines-Sep 2026
Just be careful because of the congestion at Boston you might be a little later than what is actually scheduled if you take a flight in the afternoon or evening
MichelleFlew with Alaska Airlines-Oct 2026
It’s a long flight. Wear a mask is you want to avoid catching something someone on flight may have.
MargaretFlew with American Airlines-Sep 2026
Make sure to check flight for gate change frequently.
Verified travelerFlew with JetBlue-May 2026
When you book a flight you must use your official name on your real ID. I went by Liz as opposed to Elizabeth when I booked my ticket, and I almost had to purchase a new ticket.
alyciaFlew with American Airlines-Mar 2026
Switching terminals in Boston was a VERY long walk -- dont cut your connection close if you are going from B to E
NicoleFlew with JetBlue-Apr 2026
Bring your own snacks/food. Extra legroom is nice but not really worth the extra money, unless you want free alcohol.
Verified travelerFlew with JetBlue-May 2026
At DEN, be prepared for a long walk to JetBlue check in, and a lengthy trip through airport facilities to gates.
Verified travelerFlew with United Airlines-Apr 2026
Chicago airport is super chaotic. We had come in from an overseas flight and were required to get our checked bags at Baggage Claim and recheck them for our next flight, which took a while. Then after going through a LONG customs line (again) and rechecking my bag, I was told to take a shuttle to a different terminal for my final flight. Even though I never left the building and had no access to the outside world, I had to go through security AGAIN (boots off, dump out my water, wait in long lines…) My advice is to be sure you have at least a couple of hours between flights to deal with the insanity.
MitchellFlew with Delta-Jan 2026
If you need to make a change due to weather, book early
WeiFlew with JetBlue-Feb 2026
Get to JFK early due to construction and route changes.
rsmrostovFlew with Alaska Airlines-Jan 2026
If you have a small personal bag and a personal item you will be hustled to consolidate snacks on the flight of very poor so bring your own food and if you have an Android phone you likely will have issues connecting to Wi-Fi on the plane especially if the connection was dropped in the middle of watching a movie and then you attempt to reinstate it sometimes you have to clear browsing history and cookies becomes painful
JonathanFlew with Delta-Jan 2025
Delta is great! Make sure to get to their airport early though. PHX security is a zoo.
Verified travelerFlew with Spirit Airlines-Dec 2024
Choose the early flights! Less people at the security line
ericFlew with Air New Zealand-Jan 2025
At least two hour connection Buy food pre-flight
Verified travelerFlew with Spirit Airlines-Oct 2024
The Boston airport was the worst airport I've ever been to for getting a rental car. Very little signage to tell you need to take a specific bus. Everyone around me had to ask if this was the bus & I only knew when to get off because there was a fellow passenger on the bus who was familiar.
Verified travelerFlew with Alaska Airlines-Jul 2024
Generally Alaska Airlines have very friendly and helpful people in my experience. They don’t have TVs in all planes so make sure to download their app if you want entertainment on the plane.
Verified travelerFlew with American Airlines-Aug 2024
Boston airport is very good airport. You may have to walk about 1 mile if the connecting flight is on terminal e. Lot of food options.
CarlaFlew with Cape Air-May 2024
Rockland and Cape Air were great. One suggestion: advise passenger to bring ear plugs or hand them out during boarding. Prop engines are loud. especially before take off.
slovely08Flew with JetBlue-May 2024
Terminal C is gigantic, prepare to walk for what seems like an eternity to get to your gate.
LeandroFlew with JetBlue-Apr 2024
Make sure to check what business lounges partner with Condor
DennisFlew with JetBlue-Feb 2024
If you are in groups D -F, gate check your carry on. There will be no space.

On time departure and arrival. Had to be the oldest plane in the SWA fleet but it got me where I needed to be.

On time departure and arrival. Had to be the oldest plane in the SWA fleet but it got me where I needed to be.

Flight was delayed out of BWI unexpectedly / without a reason given but otherwise ok.

I got a bit sick on the flight, and was so grateful when the male flight attendant explained to me they keep the back row open for cases like mine. He took such great care of me! I was incredibly grateful.

Friendly crew. Snacks were carb-heavy. Flight was quite delaye

The service was fine, about the same as you get on most lower end airlines. I dont understand the perks of flying them much anymore for the cost.

the flight was significantly delayed. Not much was done by the airline to compensate passengers

the flight itself was totally fine. The crew were great and very helpful. The flight was delayed, however, over an hour without a lot of information as to why.

Overall good, just screaming kids in the area the whole flight.

The crew canceled the complementary snack and drink in anticipation of turbulence that never materialized. I was counting on the drink (water) to take the the doses of medication - prescribed for my heart condition - that were due during the flight. Since no snack or meal was served on this flight, I cannot rate the food quality. Otherwise, this flight was excellent.

Really full flight, checked in ASAP and still mid Cs.

good in general food is just snack and beverages (same snacks all the time) could you try to change them?

We experienced delays in small increments that added up to more than an hour. At the gate, staff showed little concern and compared our delay with the inbound flight’s two-hour tarmac wait, which didn’t address our situation. Once onboard, the flight attendants seemed tired and unfriendly. I understand delays are frustrating for everyone, but passengers shouldn’t feel blamed for them. During the flight, a bright light above the emergency exit stayed on. It was concerning, and no one explained it or offered passengers the option to move. After landing, we waited about 30 minutes on the tarmac for a gate, then waited again for an agent to connect the plane to the terminal. From the Reagan gate staff to the cabin crew and RDU personnel, the service felt dismissive throughout. Overall, this was a stressful trip and a very disappointing customer-service experience

My flight from Atlanta to Oklahoma City was delayed multiple times. I ended up arriving in Oklahoma City nearly two hours later at around 1:50 am the following morning. This was a highly disappointing experience.

My Delta flight 2423 from Atlanta to Oklahoma City got delayed multiple times. It was originally scheduled to depart at 10:41 pm EST with a 11:58 pm CST arrival in Oklahoma City. However, after multiple delays, the flight finally departed Atlanta at around 12:40 am and arrived in Oklahoma City at around 1:50 am. What was even more disappointing was that none of the crew members acknowledged, let alone apologize, for the delays. These delays were not due to weather and were only due to operational/mechanical issues on the part of Delta. As a former Platinum SkyMiles member, I valued loyalty with Delta. However, after having similar experiences in the recent past, I'll be switching my loyalty over to American Airlines going forward. This was a highly disappointing experience.

Love Delta. I'll take connections to stay on Delta even if another airline has a direct flight.

The main issue was the quantity of the drink. The hostess gave only half cup full of the soft drink. I was thirsty and was expecting full glass like every other time.

Delta always provides stellar service. I am always impressed and will try my best to travel via Delta if I can afford it.

This flight was the flight we missed due to deltas delay at our first airport going TO Atlanta.

Wi-fi was out for the whole flight. I pay a premium to fly Delta because it has wifi and because it was out I didn’t get to work on anything I wanted to. I’ll have to make it up later this week by spending less time with my family.

I enjoyed the whole flight and the crew was amazing i dont usually fly delta

I need to note that this flight experience was generally fine but the boarding situation was absolutely a mess and there wasn’t any actual priority boarding. I rated the experience poorly because I’m am genuinely so frustrated with the crew on United taking the baggage space in first class. This flight it didn’t happen, but the last few flights (when I ironically don’t get an opportunity to provide feedback) have been spoiled because upon entering the first class cabin as one of the first few seated passengers, the overhead bins are full and ‘crew’’ tags are on the bags of those taking space. I don’t intend to infer some sort of a class or caste system but it’s absolutely ridiculous that the crew takes the overhead storage above and beyond their most loyal and lucrative customers. They should not even have economy space IMO. And I’ve gotten grief when I’ve noted to the crew the ridiculousness of the notion that the crew (who are the last off the plane) should have priority over flyers who pay. I hope you find a way to convey this message to United because it’s happening with increasing frequency and I intend to find a way to expose the specific crew members who are doing this on a flight by flight basis. (And I have a day job)

Great flight and crew. Need more legroom and DO NOT allow seats to recline.

Flight and crew were great. Need more legroom and do not allow seats to recline.

Bathrooms broken, Wifi not working, Direct TV stuck in a United credit card loop for whole flight

We arrived to Chicago nearly 30 minutes early, which was great, but then was on the ground for over an hour because the gate was not available. The issue I had was the pilot estimation was frustrating. First he said he was informed it would be 20 minutes but he said "it will probably be more like 10 minutes". After 30 minutes he came back on the comm and said it would be another 10 minutes, maybe 20. I understand he was only giving estimates but he also layered in his own gut feel. We were never told why we didn't have a gate even after our scheduled entry.

Just sat on the run way after we arrived early

New Max 10, first class seats have been shrunk. End of a 20 hour journey, it was United not Lufthansa, just glad to get home

Worst boarding experience, flight extremely delayed causing super tight connect and deplaning was a disaster as ppl were pushing and shoving to get off. Then after flying over 8 hours had to get off a job to next flight. Limited beverage service in Business class (water or white wine) no food. The plane was very cold (temperature) so uncomfortable

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.

This was a small aircraft (relatively) and we were delayed half an hour on takeoff, which is not the airlines fault.

The boarding agent and checked bag agent were both rude. It only takes a second to be kind. However, the flight crew was amazing. I got a turkey sandwich and it wasn't bad---not great but not bad. The internet was my biggest problem. This was a work trip and I REALLY needed the internet to meet a deadline but it didn't work for 80% of the trip. Very disappointing.

I tried to check in beforehand from Ireland. The Jet Blue website sent me to the Aer Lingus website and vice versa. I tried to get a boarding pass at Dublin Airport as well, but they said they couldn't help me either. I had to wait until I arrived at the gate in Boston to secure a boarding pass...it was a bit nerve wracking.

Great flight. Best in years. Very clean craft. Easy boarding. Communicative pilot. Friendly flight attendants. Absolutely smooth take off, in flight and landing. Very comfortable seats. Smoothest flight I've experienced in years. THANK YOU JET BLUE!

I was asked to pony up an additional $239 (over the $735 paid originally) for a one way middle seat, which was very uncomfortable. Where did you expect me to sit?

Jet Blue sevice was good. Just don't understand why they charge for earphones to listen to flight entertainment. Other than that, everything was excellent.

Mostly good, flight take off in time and land earlier I can’t ask for more..

The crew was not nice this time. I asked for a drink one time and the girl didn’t say anything to me and just got me the hot drink while walking super fast to the back. We were sitting in the back and she wasn’t doing anything except socializing. She was upset I asked for something and she had to do her job. I also didn’t fully have it in my hands when she handed it to me so it was dangerous. She was abrupt and rude. She wouldn’t allow for people to spread out like previous flights we had been on if they were empty, and there were empty rows. It was strange and she enjoyed being angry at us.

The plane was FREEZING COLD. Like I was wishing I'd brought gloves. Is this how JetBlue sells more blankets? Other than that, all fine. Crew just as nice as usual. A flight attendant asked (who? The pilot?) to have the air turned down for a great number of passengers who were as cold as I was. They (again -- who is "they") did not.

Flight was fine, but I was annoyed to have to pay for luggage again. We had paid for our luggage on our first two connecting flights with SATA Azores Airlines, but had to pay for luggage again with JetBlue at JFK airport. For one trip we paid over $500 for two suitcases to travel from Azores to San Francisco.

Everything was great the only issue was lack of Wi-Fi

Cabin staff were very disengaged, spoke with no eye contact, dismissive. Disappointing compared to my United experiences.

awful delay, awful communication, zero updates throughout the experience of a giant delay

It was decent, there was no WiFi on the flight but the FA’s gave everyone a warning once we boarded the plane. Unfortunately it didn't give me enough time to download my entertainment content.

On Time. AA is late due to maintenance all the time.

Seats were very tight for a 17 hour flight. Baby cried for 15 out of 17 hours.

Flight attendant super rude demanding I remove my carry on baggage from overhead and place under seat. I stated I am an ADA passenger and need the leg room as the seats are very tight. That’s why I boarded early for the extra time to get situated. She said, we need the space. I replied “How can that be as only a few passengers have boarded so far? I am executive platinum status so I understand the rules and you are discriminating against ADA federal law. Please stop”. Her answer… then you should find another flight! Not ok. Addressed with senior flight attendant. So unprofessional and discriminatory.

Perfect from check in at the airport to the flight all staff were very friendly The plane was nice and clean and modern Because I’m here in the UK to visit my Dad who’s critically ill the details of me getting here were very important and nice to see staff being pleasant and professional

Both departure and return flights had mechanical delays. Their planes are antiquated resulting in a two hour flight taking almost four hours to complete.

Flight attendants were pleasant and helpful. Pilot gave fair warning about turbulence.

It was close to its perfect the flake could be took off early, landed early, didn’t have to wait for my daughter stroller luggage came out quick, very efficient, very good flight
