You can look at the below website to see how long it typically takes to be processed through passport control at most US airports - they provide both the average and max wait time at different times of day.

Which airport and from which airline to which airline, if it’s a large airport and you are changing terminals it’s different than a smaller airport.

Usually, the hangup is immigration. Not customs..

Check the averages for whatever airport you're connecting through..

Personally, nope, 90 minutes isn't enough. Immigration, baggage wait, bag drop, security, then getting to next gate - nope.

GE, carry-on only - maybe. Security can be the backlog though...

It really depends.

You have a chance to make it, but I would not bank on it.

Maybe, maybe not

“Will 90 minutes be sufficient time re- entering into the US to catch a connecting flight.?”

I have global entry 90 minutes is plenty of time for me at any airport.

Since you didn’t mention it I’ll assume you don’t?

You also didn't mention which country you're coming from. Sometimes you clear US immigration and customs before taking off, depending on country and time of day. That would make arrival in the US a breeze.

Hello,

A 90 minute connection time works depending on the airport you are connecting through. Larger airports will need more time. If you have Global Entry, that makes the immigration process much faster.

Unless you provide more information, all of these responses are pretty much guesses.
