Re: WN cutting 20 non-stop routes Jan 6

I'm surprised they are retiring 737s. Are they sourcing 738s from anywhere to cover the gap, or just going without and shrinking capacity? I would imagine they don't have a choice but to retire these planes. Retirements are usually timed to occur at the next heavy check due. WN outsources all of it...
