Today I had to walk a mile, literally, in the Los Angeles airport just to arrive at the boarder entry & customs. There were zero bathrooms between my plane and baggage claim. Luckily I had anticipated this and made sure I wasn’t in desperate need of a bathroom stop when the plane landed.
I can only assume this is on purpose, but it is rather annoying nonetheless. Just remember to be sure to use the bathroom before you land on future flights that involve passport checks and customs.
