Not necessarily. We won't hire today for planes due to arrive a year from now. It would mean however that we'd have to ramp up hiring this fall.
Now upgrades, they would likely have to ramp up in the next 2 bids. (But as you know that can be added after with a supp bid)
If we see an unusually large list of upgrades on the June or Septemver bid we will know something is a foot.
