My 22 month drought has ended! BOI-SLC oversold by six today, they ended up needing five.. $800 voucher for a horrible reroute that includes a red-eye flight SEA-DTW, so I'll earn it. Every flight to SEA and SLC is oversold for the rest of the day, all due to customers coming over from cancelled Southwest/American/United flights due to the MAX8/MAX9 grounding.
