When I was frequently traveling to Altus, Oklahoma, LAW was the closest airport to Altus that I could fly into. However, it’s still an hour’s drive away from Altus and required a layover through Dallas/Fort Worth (DFW), so most of the time it was just faster overall to take a direct flight to DFW and then drive three and a half hours to Altus.

It’s a pretty small airport as far as commercial service airports go—effectively a single gate (whose security checkpoint doesn’t even open until half an hour before the flight) with outdoor boarding by airstairs.
