Saaaayyy... Wouldn’t a route to Hawaii be quite a coup for southwest? Then again, I love Southewest for hour-long flights; on an eight-hour flight, that bag of peanuts is gonna seem pretty skimpy. :^D
South West can’t fly the route themselves. They don’t have ETOPS approval for their aircraft. That’s why they used ATA and also why they’ll probably find another partner instead of trying it themselves. If SW was flying it though I’m sure they would give you an extra bag of peanuts! ;^)
