Hey all,

I had to make a last minute change on a flight from SAN to YYZ with a one hour layover at IAH in between.

I am concerned about a couple of things:

- I am not used to the IAH airport. Because the second leg of trip is from IAH to YYZ, will it be different terminals?

- I will go through security once at SAN. When I get to IAH, will I have to go through it again or can I just go to the gate?

Thank you.
