I'm flying via the U.S. for the first time from Europe (Munich, Germany) with United and I wanted to know if I need to get my bags at the transit airport (IAH, Houston) and check them again for my connecting flight to Cancun, Mexico or if they will be forwarded?

Also I wanted to know if I need to go through immigration at the transit airport?

Thanks in advance for your help Simon

Yes, you'll need to go through the US customs and immigration, and that includes taking your bags. You'll re-check them in with United right after the customs (look for "connections" sign).

They'll probably be tagged all the way to Cancun when you first check them in in Munich, so make sure to leave the tags intact attached to the luggage when you pick them up to go through the US customs.

  • Alright, thanks for the fast and thorough answer. Do you think 1 hour and 45min is enough time to do all that?

    @s137 if they sold you the ticket then United think it is. It depends on how long the immigration line would be and whether your flight is delayed in MUC/late into IAH. If you miss the connection, United should take care of you.

  • Is this a single ticket with one PNR that you bought from United? Or two tickets on United that you bought in separate transactions? Commented Aug 21, 2022 at 0:00
  • Its one Ticket with one PNR.
