Yes, but how often and under what circumstances will the other carriers put you on another airline? The original delay was 2.5 hours and her flight was not cancelled. I seriously doubt UA, AA, or DL would have interlined their customers in this situation. And, of course, flying from HOU to AUS, no other airline could have gotten her home in any timely manner.
