Flight from Barcelona-El Prat to Boston

MikeFlew with TAP AIR PORTUGAL-Sep 2026

The throne seats (rows 2 anf 4) are single seats, so no being the climber or" climbee" in these rows. The other seats in business class are 2's so the window seats have to climb over the aisle seats to use the bathroom. If the aisle person is reclined and sleeping, it might be a challenge. Therefore, my wife and I (fortunately) were in row 4. The throne seats also have extra space.

BudFlew with Delta-Jun 2026

Boston is one of the most difficult airports to navigate when returning from overseas. A long walk thru the overseas terminal E to customs, then after waiting in the line to clear customs, you have to retrieve your checked bag and take another long walk to the domestic checked bag location. Then you have another loooong walk to the domestic terminal (A or C) for your connecting flight. A bus is provided, but they are infrequent and often too crowded to board. All in all, you need about 90 minutes between flight (minimum!)

Verified travelerFlew with TAP AIR PORTUGAL-Aug 2026

If you are upgrading your flight, MAKE SURE that you speak with someone at a ticket counter or baggage check-in counter to make sure that they know your same bags are connected to the upgraded ticket, otherwise they will lose your luggage like they did mine!

Verified travelerFlew with British Airways-Jul 2026

I still prefer BA for London-Boston but all services, especially food, have been declining over the years. Boston has some of the longest walks in Terminal E. Small carts like they have in many European airports would do a lot to help especially senior passengers.

LAURELFlew with Iberia-Jun 2026

DO NOT SIT IN A SEAT IN FRONT OF AN EXIT ROW.

BijanFlew with TAP AIR PORTUGAL-Jul 2026

Use a direct flight. Connecting flights are brutally exhausting.

Verified travelerFlew with British Airways-Apr 2026

Give yourself plenty of time to go through security especially if you have to go from one terminal to the other. 90 mins minimum

Verified travelerFlew with Aer Lingus-Apr 2026

Very convenient to do US immigration before the gate.

Verified travelerFlew with Condor-May 2026

Be sure to be there early. Lots of long lines especially for flights to the US from Frankfurt, due to security.

JimFlew with Aer Lingus-Mar 2026

The A330 is very loud in the back; better to book a forward seat.

TinaFlew with Icelandair-Jan 2026

All went smoothly for the return fligh from KEF to BOS. Take advantage of the duty free which has some prices better than in the city!

TimFlew with Aer Lingus-Jul 2025

Check your bags if traveling to the US if included / possible. It was a long walk for the flight connection and we did US customs and immigration in Dublin, not Boston, which was a first for us.

Verified travelerFlew with British Airways-Mar 2025

Try to get an aisle seat and walk around the plane as often as possible. Your legs will thank you

YaneliFlew with Aer Lingus-Apr 2025

Arrive early (3 hours) because lunes get very busy.

ShawnFlew with British Airways-Dec 2024

Know that gates are posted just about an hour before takeoff and it takes a bit of time to actually get to the gate. If you make a mistake there is no train back- you have to walk to the correct area and that are at least 10 minutes apart. Make sure to have ALL liquids ready to place in the tray at TSA

HFlew with Azores Airlines-Dec 2024

Expect to walk up the stairs on the plane as the ponta drlgado has no air bridge

Sheena-Jun 2024

Be easy for the longer lines for passports and going through customs. Give your self plenty of time.

ErikFlew with Vueling-Jul 2024

Check in online if you must fly this airline. Avoid excess weight (up to $250 per bag!). Better yet - fly another carrier. Single worst flying experience of my life. And I easily fly 150,000 miles every year with all types of carriers.

Verified travelerFlew with British Airways-Mar 2024

If you are arriving on a late flight check in to an airport hotel at Logan. Good choice, easy access and good start to your trip

BridgetFlew with ITA Airways-Apr 2024

Rome is an excellent airport. If connecting through Rome, know that there is a customs station you need to go through before your gate.

HeidiFlew with Lufthansa-May 2024

If you’re changing planes in Munich leave more than 1.5 hours between flights. Our first flight was late so we had to rush to next and it was quite a distance plus you have to go through passport security again.

CassidyFlew with Iberia-May 2024

Check to make sure the airline you are booking through is not subcontracting it out to a janky airline to cut costs.

Verified travelerFlew with Finnair-Dec 2023

If you’re looking for a hassle free and good customer experience, avoid BA; Fly American. As soon as you board the plane, set your watch to local US time to help adjust to the time difference.
