Flight from Paris Charles de Gaulle Airport to Boston

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!)

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.

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

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.

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.

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

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.
