Thanks for the reply. Just to clarify, if it would take one bid to get from EWR to IAH, how often do those bids occur? Is this referring to the system bid that seems to run every few months? Are you guys thinking if SFO opened up for the 737, would that have a potential of making a base like LAX or SFO even more obtainable within a year or so? Again I understand this is all best guesses here and anything can change in a second, but the general rule of thumbs are helpful none the less.
