I am by no means, a frequent flier but I found a $20 difference in the flights I booked to Las Vegas. We rescheduled our trip to Las Vegas going from Baltimore Airport via SWA. I booked the flight(s) round trip for 2 people. The flight out leaves BWI at 7:10pm and arrives LAS at 9:20pm. The ticket price per person on SWA site is $157.00. IF I book the same flight/time as a single person it is $137.00??? Why can't I rebook the flight as 2 single fliers and save $40 or contact SWA and try and get the lower fare?
