First time through IAH...long enough layover?
 

I'm trying to take the redeye 1743 SFO-IAH then connect to 2606 IAH-MEM with a 56 minute layover.

Kayak tells me 1743 is only 70% on time...do I chance it? I'm not going to check a bag, and have changed terminals at LHR at a good 10min/mile run, but having never been to IAH...can I make it? Do I factor in the chance of lateness?

Thanks!

56 min should be fine.

It is a hit or miss.
If the flight is on time then no problem at all.
SFO night flights are notoriously late.
I find that either they are on time +/-15 min or they are totally late (hours).
I would go for it.

You're gonna be going from terminal C to B. Not fun, but doable.
