I'm flying on 2 Feb and they only have one flight to Houston instead of the usual two. Or maybe they have 2 and the other is sold out since the Super Bowl is that weekend?

First is selling as F, not A on that date and there aren't 5 seats available. I'm relocating with my family (have to get back inside the US before Trump builds the wall!!) so an ex-EU isn't practical and I'd rather have a non-stop flight.
