Flight from Paris Charles de Gaulle Airport to San Francisco

ManyiFlew with British Airways-Jun 2026

London airport is huge - it took be an hour to transfer from one gate to another gate in the same terminal. Plan accordingly.

DeannaFlew with TAP AIR PORTUGAL-Jun 2026

Arrive 3 hrs before flight time to allow for new check in process. Facial recognition is now being used.

RobertFlew with French Bee-Jun 2026

Extra time for the airport, have your devices fully charged.

GabrielaFlew with Scandinavian Airlines-Jun 2026

Go very early to go through customs. very stressful otherwise. Next time i will give myself 3-4 hours as lines were ridiculously long at Copenhagen airport

Verified travelerFlew with Condor-Jul 2026

Make sure you have over 2 and a half hours layover or you WILL Not make it through customs in time. Do Not fly on Condor.

RobertaFlew with United Airlines-Mar 2026

If flying from Paris to SFO, I would recommend if you are not familiar with either terminal to do some research: CDG is very well organized for signage and helpful general customer service. SFO is not as well organized for signs, and the people who work there (at least upon the returning/customs area) don't seem as cheerful. The TSA agents at SFO were super nice to us when we departed! Their French counterparts are not as pleasant - they are really pushing hard to get you through security. So, again, familiarize yourself as much as possible with the different systems to herd you through to your plane and getting in and out of the terminals, and you will probably have a better experience. I recommend looking at online videos and terminal maps, along with transportation options.

Verified travelerFlew with Lufthansa-May 2026

I didn’t receive email with the reminder to check in 24 hours before the flight. It would be helpful to get reminders to check in and emails with info/updates with the gate number. I do appreciate emails confirming that the luggage was dropped off. It’s disappointing that it’s impossible to choose a seat without having to pay a free. The check on luggage free is quite high too. It’s Unfortunate airlines charge to check in a luggage.

JanieFlew with SWISS-Jan 2026

If you need to do an overnight layover, Grand Hyatt at SFO is perfect and has a 24 hour cafe!

AntonFlew with United Airlines-Feb 2026

United has a cool arrival lounge in london but it is a bit hard to find, after customs look left

ZeynepFlew with Scandinavian Airlines-Dec 2025

The lines are long. Make sure to get there at the recommended time

PeteFlew with ITA Airways-Nov 2025

“Comfort economy” is worth it. Noise cancelling headphones/earbuds are important, along with an eye mask.

MichelleFlew with Aer Lingus-May 2025

Make sure you arrive well ahead of the flight. We were lucky that security lines were pretty short but they could be very long and you do US customs and security in Dublin.

AlastairFlew with British Airways-Feb 2025

Make sure your free checked luggage is for outward and return flights.

NinaFlew with Aer Lingus-Nov 2024

Make sure you include extra time to pass through US Border Control if you’re flying to the US! Also Aer Lingus bag drop closes 75 mins before flight departure for long haul so bear that in mind!

Verified travelerFlew with United Airlines-Sep 2024

Download all your music. Add shows and movies to your queue. Bring short so you can relax. Bring long charger cords.

SunnyFlew with Turkish Airlines-Nov 2024

Turkish lounge is so good, however receptionists are anything but receptive: they were inattentive and rude x 4 Airport is very large for a tight international transfer if inbound flight is 30 min late

Verified travelerFlew with United Airlines-Jul 2024

Fly either Business class or Premium Plus. Realize Business is unaffordable for most but Premium Plus is worth the extra fee.

AmirFlew with TAP AIR PORTUGAL-Jul 2024

For any flight that's part of a Multi-City flight plan, don't miss it. Otherwise, all your remaining flights on that plan will be terminated.

Verified travelerFlew with American Airlines-Mar 2024

Heathrow is vast, allow plenty of time to drop bags and go through security. At San Francisco the immigration takes a bit of time and we had to wait around 1.5hrs, bare this in mind when booking car rental. The is a shuttle train from the airport to the car rental area which is very slick and efficient.

HenryFlew with United Airlines-Apr 2024

connection took much longer than I expected; need 20 minutes between taking a shuttle bus and pass through custom before you get on your flight

Ana-MariaFlew with Iberia-Mar 2024

In London triple check your flight they have multiple leaving for the same destination once - it is easy to get them confused

Verified travelerFlew with British Airways-May 2024

Terminal 4 in Madrid is not well signed to tell where passengers need to go after each step. Planes are far from the Terminal. Baggage check in is slow.
