Wife and I just traded in our Sapphire Reserve cards for United Club Unlimited cards. Out of San Antonio, most places we fly direct (Newark, Dulles, Denver) are on United and any connection is usually in Houston where we camp out in the club away from the masses. We've had good experiences on United lately, especially considering the other major carrier out of here is American Airlines, who flat sucks donkey dick. Southwest annoys me that you have to use their website/app to book flights instead of just allowing them to be aggregated with the rest on Google Flights/Kayak. I've also rarely gotten a cheaper flight with SWA than United or Delta.
We were flying to JFK for our wedding in July and American's bag check lanes were wrapped around the terminal and we missed our flight. United had no line, so we went over and talked to their reps at the kiosk and they told us if we could get to Houston in 4 hours, we could get a direct to LGA. We hauled ass and had another good experience with United at IAH with zero delays. It'll take a lot for me to hate on United after that.
