One of my favorite airports in the US. It is large, but not TOO big where it takes forever to get around. Good selection of stores and restaurants, and most importantly, it has an American Express Centurion Lounge! Even if I am waiting 30 minutes I am entering that lounge!
I've been in-out of LAS at least 50 times in my lifetime especially with my parents living here and I (knock-on-wood) have only had good experiences here in terms of very few delays, if any.
