Good boarding process. (Nice to be able to buy Group 2 boarding option.) Plane was clean. Tried to avoid full flight by flying on Saturday, but plane was full anyway. Gate area in Houston should have charging options. Should be a lounge for people with American Express Platinum Card in Houston Airport.
