Headed home for DEN, I was at Hobby yesterday during all of the uncertain weather. The airport was on a ground stop for more than 90 minutes. The Frontier terminal crew handled it extremely well. They kept us informed, were cool and collected and managed to pull off an inbound and outbound turnaround in less than 35 minutes. Frontier was the first plane in and the first one out... many other airlines diverted flights but F9 circled waiting for an opening. While we were on board the flight to DEN, the FAs kept all connecting pax apprised of their continuing flights and on landing in DEN we let them all get off first. I heard in the concourse that they actually held a flight for a couple of connections. All in all, super work by all concerned! I'm so glad that I wasn't on UA or SW.
