Flight from Barcelona-El Prat to Washington Dulles Airport

Verified travelerFlew with ITA Airways-Sep 2026

Dulles and Rome airports were very crowded and difficult to get to your gate. Allow sufficient time for connecting flights.

Verified travelerFlew with SWISS-Jul 2026

The Swiss are very efficient with passport control. They have devised a system which is quick and helpful. It would help tourists if they could explain their system so tourists know what to do in advance of reaching the airport. We had a very short connection. Our son’s had travelled that same way the day before and It was because of our his explanation that we could make our flight.

Juan GFlew with Air France-Jun 2026

Due to the excess of hand luggage, the airlines are offering to take it at no cost. What provides a lot of comfort.

Verified travelerFlew with Aer Lingus-Aug 2026

Multiple security checks and immigration at Dublin airport so even 2-3 hours of layove is short.

DonaldFlew with United Airlines-Aug 2026

Check in online. Check in desk in Edinburgh is chaos. Not the case with Delta or KLM.

Denise and ScottFlew with United Airlines-Apr 2026

Bring an eye shade. Although the plane is dark for parts of the flight, it helps to sleep.

OlgaFlew with United Airlines-Mar 2026

Make sure you have close to 2,5 hours between your connecting flights!!!

Verified travelerFlew with Icelandair-Mar 2026

Be sure to dress warmly when leaving Reykjavik!! --Especially during the Winter months! Did noticed an enclosed overhead ladder(though still required us to be outdoors to board) was used yesterday . Hopefully someday Reykjavik would be able to have more concourses gates

SabuFlew with Turkish Airlines-Dec 2025

If you have a long layover in Istanbul, take advantage of the free hotel stay that Turkish Airlines provides and explore Istanbul.

BobbieFlew with TAP AIR PORTUGAL-Dec 2025

To definitely go to the airport more than 3 hours ahead of your flight time because Lisbon airport js very poorly designed with no self checking devices and shortage of staff to assist you. Long long lines for going through security, 3 hours or so just for that. Many flights were missed because of that so go at least 5 hours before your flight to be able to make it

Verified travelerFlew with Lufthansa-Nov 2025

Pack a jacket since you need to deplane in the open to get a shuttle to main airport

Verified travelerFlew with Lufthansa-Nov 2025

Be prepared for very long distances to the gates.

ROSSFlew with Lufthansa-Jun 2025

Download the LH Entertainment app before the flight so you can watch content on your personal devices.

Verified travelerFlew with Turkish Airlines-Jul 2025

Be prepared to have a second security check when you arrive at your gate. They also don’t make boarding announcements so you have to figure it out yourself.

Verified travelerFlew with Lufthansa-Jun 2025

Buy your seat ahead of time if you don’t want to be stuck in the middle or back of plane. It’s a shame that airlines have this added cost but it’s hard to avoid paying especially if you need to get off the plane quickly

Verified travelerFlew with Austrian Airlines-May 2025

Long walks to high gates so come prepared for a walk, especially if your older or infirm.

Jan PaulFlew with United Airlines-Dec 2024

Washington is one of the nicest layovers, nice quiet and not too busy. Walking from plane to customs to plane never went that fast compared to the bigger airports

Verified travelerFlew with United Airlines-Dec 2024

Bring your own food AND drink on the plane with you.

Verified travelerFlew with Aer Lingus-Sep 2024

Allow a full 2 hours for check-in and boarding.

Verified travelerFlew with Lufthansa-Aug 2024

Make sure there is more time in between your flights

ElidaFlew with United Airlines-Jun 2024

No bathrooms before customs. Takes about 45 min to an hour for luggage to get from plane to where I can pick it up to transfer it over. Area feels dirty

Verified travelerFlew with Air France-Jul 2024

Don’t use Paris for transiting from another airport. It is not transit friendly. Use Munich of Frankfurt instead.

LindaFlew with Turkish Airlines-Apr 2024

Get there early! There are more layers of screening than in the U.S. We were handled by 10 different people on the way to the gate. Lines can get long.

JenniferFlew with United Airlines-May 2024

Good luck with the flight, make sure you eat before you board the plane because that's a long flight for the food that is served on that plane.

Verified travelerFlew with Lufthansa-Apr 2024

Take more time than you think you need to get through customs. 2 hours isn’t enough.

Verified travelerFlew with United Airlines-May 2024

Frankfurt airport falls short in customer service and care, particularly during the multiple security checks, making it challenging for travelers to navigate efficiently. With layovers of less than three hours, there’s a significant risk of missing connecting flights due to the airport’s procedures.

Verified travelerFlew with Scandinavian Airlines-Jan 2024

Bring your own headset if you want to check out the free entertainment on the ground before the cabin crew provides it. They brought it after the plane reached cruising altitude, about 25 minutes into the flight.
