I took this deal last year before a flight on Southwest (to a city that Frontier doesn't serve) - unlike Frontier, Southwest does not extend the perk of priority boarding to traveling companions, so you board early and play various games to try and save a seat while your SO stands in line. Add to that the fact that the airport (PHL) had a 45-minute security line with _no_ enforcement of the premium line, and all this deal really did was remind me why I fly Frontier whenever possible over Southwest.
