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

Insights shared by verified travelers who flew to Portsmouth 
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.
Verified travelerFlew with Spirit Airlines-Feb 2024
Give yourself a little extra time at the larger airports. Long lines at tsa

had to check bag at gate when there was still overhead bin space. As usual the WIFI didn't really work.

Terrible delay today. also, waited 90 minutes for baggage to unload in Seattle earlier in the week.

Like new plane. Great crew. Comfortable. Clean. On time. Happy employees. Good organization and control of passengers.

Flights delays were communicated timely and helpfully, but there was a significant delay without any real effort to make up for that. Also, the in-flight WiFi was very spotty. That said, this was my first time with Southwest and I was quite happy with the service and staff otherwise.

Delayed and once landed waited very long for the luggage

Nice managed … it was a smaller plane, so the seating wasn’t as comfortable.

The Southwest airline was ok. A big thank you to Kayak team (David), who worked with me on Sunday afternoon to rebook my travel from Burbank, CA, to CVG. My original flight on Sunday was delayed, so I had to cancel Sunday flight and rebook my travel to Monday. Could not have done it without help from David from Kayak team. Ante Soda GE Aerospace

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.

Flight was delayed at airport with large backlog and WiFi was spotty

I don’t like mushrooms and that’s all they had with pasta

I Love Delta but one of the flight crew training in courtesy snd hospitality.

I don't know why the crew decided to board 15 minutes early without informing anyone not at the gate. Why would you have the app send a notification that we're boarding on time, instead board early, and then rush me to the gate. Then have me check my carry-on when I specifically packed my bag as to not do so.

Could have been on time and not missed my connection

Really hard to tell what was happening after my flight got delayed five times

Flight was delayed from San Diego due to being overweight for weather conditions. We missed our connecting flight to our final destination due to the delay, as well as the connecting flight leaving before the scheduled departure time. We missed the connection within 10 - 15 minutes. We were booked on a later flight arriving 7 hours later. There were 7 passengers sharing the same originating and connecting flight.

Horrible, mismanaged ground issue resulting in a long delayed, next flight left early, waiting extra 7 hours in the airport, screen did not work

Wifi on this flight was very sketchy and not available for most of the trip.

I’m on this flight every other week. Same flight, same day of the week, same time of day… Multiple times there are issues getting flight plan registered and FAA approved r to take off. PAPERWORK This is exhausting and it sucks.

Very disappointing that on an international business class flight they would not give me access to the lounge in Boston. They said it was because it was a codeshare flight. International business class should include lounge access regardless of codeshare.

They did not have free WIFI and I was not okay with that!

Flight was on time, clean, etc. Despite connecting to your wi fi I was unable to use your app to watch entertainment.

Awful!!!. I do not recommend United. The flight staff are unhappy and don't attempt to make the passengers feel comfortable or welcome. The food is not edible, and the seats are miserable. My expensive luggage was destroyed, and the ticket prices are too much for the experience.

Even though the incoming flight was delayed by 20 minutes they managed to get us to SFO 15 minutes early.

On time, easy boarding. Anytime you sit in an economy seat, it’s uncomfortable. New plane and the bathrooms were in the galley at the back of the plane which seemed odd.

It was fine for the most part. But the volume on the announcements was way too loud, and the cabin temperature was chilly. We had the hardest landing I've ever experienced- I think it hurt my back, and the tires squealed when we touched down.

Great, except the canon was so cold. Even the flight attendants put jackets on

Did not like the check in guy quibbling over a couple pounds at the luggage weigh in

Just having a little bit more legroom would've been nice.

The forward head smelled putrid and urine soaked, worse than any head in even transoceanic flights. The wifi stopped working after about an hour of flight.

Wifi was good on the flight from DCA to Dallas and terrible on the flight from Dallas to Tucson. The forward head in the flight from Dallas to Tucson was putrid smelling entirely urine soaked. The flight from DCA to Dallas was delayed by almost 30 min with a plane change.

As per usual for my flights with American Airlines, One flight was very delayed and caused me to miss my connection and they moved my flight to another day. I called customer support and was moved back to my original day but different flights. My layover flight was delayed by an additional 30 minutes while the flight crew confirmed that the plane was airworthy. Ultimately, it is less hassle to drive 10 hours than to fly 6 hours with American Airlines. I recommend my friends and family to hitch hike over taking this terrible transit.

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.

I've never seen such poor lack of information at a gate station in 69 years. The flight from COS was to depart at 12:37pm. At boarding time, the gate agent in the microphone mumbled something completely unintelligible. I understood one word. "mechanical". Nothing else. Absolutely nothing else was reported for the next 1-1/2 hours. Past the time for departure, at 12:37pm, the gate agent simply walked away and the station was left unattended, as all of the passengers waited expectantly. The board still said that the flight was ON TIME. That was hard to believe since it was then well past 12:37pm and we all were sitting at the gate and there was absolutely no gate agent anywhere in site. I stopped an employee who was standing somewhere else and said that we can use some information. Much later, the same gate agent said that he will have information for us about 5 minutes but he "doesn't know any more than you do." Of course, five minutes came and went and he did absolutely nothing. One and a half hours after 12:37pm, he opened the door and began boarding. No explanation, no apology. Once we were boarded, the same happened on the plane. We sat. No explanation, no apology, from any flight attendants. Finally, finally, a pilot apologized and explained that there would be a delay. WELL NO KIDDING !

American Airlines put the food on the wrong plane which had already taken off by the time we took off so we had no food on the plane.

With weather and severe delays it was disappointing we didn't receive any compensation for the 5 hour delay. Not even a food voucher.

ATL to CLT return flight. Delayed way too severely. Had to cancel the return flight.

I've flown American several times this summer and I have yet to get a flight that leaves on time. However, a delay is better than a cancel. So far I have had four canceled flights and two delayed flights

Every time I fly American they end up delaying the flight significantly and claim it’s due to weather, however, it was a beautiful clear sunny day in Dallas today. Unfortunately, these significant delays occur more often than not which I don’t experience on any other airlines. Yet American Airlines consistently faults the weather and never holds itself accountable for the poor and unorganized service. I will keep my business with Delta, United, and JetBlue going forward. American Airlines should not be part of the “Big 3” considering United and Delta are light years ahead. JetBlue is also much ahead of American. American needs to step up big time

Good experience with this flight. Boarding was smooth with no issues. The short flight was good with quick drink & snack service. Nice easy way to get back from DC.

Very good flight that left on time and arrived earlier than anticipated, which was a plus! The crew members were very welcoming and helpful. However, the temperature on the flight was very cold - almost to the point of extreme discomfort. Additionally, requiring passengers to pay $8 for headphones to access the JetBlue entertainment was disappointing. Those earbud jacks are not used with most technology and would not be able to be used. There was no option to use Bluetooth for my own earbuds. Beyond those inconveniences, the flight was good.

My original flight was cancelled. My replacement flight was delayed over 2 hours. I lost my whole day in NY

Delays were crazy long (over an hour) both for boarding and baggage claim

awful expereince. boarding was a mess and not communicated, then we sat on a hot plane and were at risk of getting kicked off

2 hour delay and a lack of air conditioning on the plane. Not a good combination

Fabulous! This was the first time we've flown with JetBlue and the entire experience was flawless!

First time flying JetBlue and my perception changed. Love it.

Poor, had a 5+ hours delay. Kept sitting in the aircraft with three kids. It was terrible

The plane was filthy and worn - the seat pockets were stuffed with tattered food and torn pamphlets. The cleaning crew that came on as we were deboarding were grabbing handfulls of trash and perfunctorily wiping down tables with dishrags. It's been a while since I flew Jetblue and it used to be a great experience. After this flight I will avoid flying Jetblue again if there is any alternative.
