I am sure you are right. BUT we have flown SWA...just guessing 2-3 times a year over the last 20 years and have never had more than a 30 min delay (vast majority of flights were on time).
On our outgoing Frontier flight, we were delayed 8 hours with no announcement at the airport at all about the delay. Nothing. Angry mob scene was forming. On the way home, the airport personnel kept us fairly well informed about the delay but once on the plane, there was no beverage service. Not even water. And the flight attendants never said a word about it. It was just bizarre compared to our experiences on SWA.
