Hawaiian has a great service from the states. It’s like saying Greyhound will put Southwest out of business if they started competing directly on city pairs.
I can barely withstand a 30 min flight on Southwest, let alone 6 hours next to Bubba and his 6 kids. What I would be more worried about is the kind of people Southwest will bring to the islands. I don’t think their are enough Motel 6s and RedRoofs to cover the inflow.
Hmmm. That may be a good investment now that I think of it.
