That is a really good question. And at the risk of a "cop out" myself, I will say that I do not know. We have rates on every airplane under the sun it seems, and personally I think we are shooting ourselves in the foot because of - the way it has always been done- being some seat/weight/speed crap formula.. which is fine if you have a bunch of your biggest airplanes... but in our case, we don't. Forgive the drift. So... since the guys that will be negotiating this in the future for US will probably do it the way it's always been done.. I would think that once our 737 rates exceed yours, your 737Max rate should probably be 10-15% above that.. but that is just an off the cuff supposition. Set the bar for the next one, that's what you need to do.
