Flight from Barcelona to Seattle

KristinFlew with Lufthansa-Sep 2026

Have a two plus hour connection. Munichs airport is poorly run and a one hour connection is not possible.

CJ & LisaFlew with British Airways-Mar 2026

Get up and move around as much as possible and wear compression socks.

BruceFlew with Icelandair-Mar 2026

Prepare your own food. During 8 hours of flight, they don't five any snacks nor meal. You have to buy everything, including soft drinks. Choices of sandwiches is only 2 and very pricey. I never experience that you have to buy meal for the long flight.

Verified travelerFlew with Aer Lingus-Dec 2025

Dublin Airport has US Preclearance, meaning you go through US Customs and Immigration before boarding your flight. If you're connecting through Dublin, this can catch you off guard. You'll need to clear passport control twice between gates, so plan extra time for short layovers.

Verified travelerFlew with Scandinavian Airlines-Jun 2025

Copenhagen is really laid back. Plenty of space at the gate. However, not a lot of shops. They have a self serve 7-Eleven! So, if you have the time and are hungry, eat before you go through to the gate.

NickFlew with Lufthansa-Dec 2024

Be early at the airport so you will not get stuck at the document check that is done mainly for flights to the USA
