Food for thought. If living in Hawaii is what is at stake and you are factoring in AK maybe having a Hi base.....Hawaiian you know you will always have that option. Every mainland airline that has ever had a crew base in Hawaii eventually closed it. Also, you would be limited to what ever you could hold at the small base and not be able to pursue the more options available at other domiciles. Unless you wanted to commute.
On one hand, at AK you could commute easily enough and bid trips to Hawaii, you're home getting per diem on work days, which isn't bad. We have quite a few pilots that commute to the NW and bid PDX layovers to be home. But on the other hand commuting is still a bummer.
I will say this, although I would be careful about giving up a number with AK to start over at any airline, all the airlines left will survive. The music has stopped with airline liquidations due to overcapacity and we (the handful of airlines left) are the ones left with a chair. Mergers are still possible but I really think HA and AK have a strong enough niche that we will both dodge that bullet. The reason AK's stock is doing so well is not because it's a potential takeover target, it's doing well because it has a strong niche as Alaska Airlines and is well managed.
I will say this, If you really want to live in Hawaii, any number with Hawaiian is a good one. Personally, I would rather be an F/O with Hawaiian than number one at any other airline, personal choice, but I am a lifestyle over money person.
Anyway, more food for thought to confuse you!
