Hi all,

I am making my first ever redemption flight - return being SJU - IAD - BRU - EDI in econ, then 1st and finally biz on Jan 20th

Question is: there is just over an hour transfer in Washington Dulles to get the BRU flight.

What's the thoughts of experienced United transferrers?

Also, is SJU inside or outside the USA for immigration. ie do I also need to enter and leave the USA in Washington even when in transit. Have missed connections in Miami like that.

Many thanks.
