How does Passbook know when you are near a particular gate in any given airport?
It wouldn't. It would simply know that you're near your departure airport around the time you're supposed to be and it would show a notification.

I find it an odd assumption that passbook ignores NFC.
It seems to me while it could operate without NFC support would add a lot of scope for it to expand.
That's ok. NFC hasn't really gained any traction yet. Why bog down the battery and OS with something that hardly any stores know how to deal with? We know Apple doesn't play like that. Look at LTE.
What I think would be most clever is to include an NFC chip in the iPhone 5 (or whatever it will be called) but not have it turned on. Apple could start pressing retailers and other places to use NFC and then activate it alongside the release of the iPhone 5s (or whether it will be called). This will basically allow for apple to get an install base established to use as leverage to build partnerships. That is what I would do, however, I'm no Tim Cook. :-D
Why wouldn't it be enabled from the start? What's the benefit?
Expand meaning that passbook could work in conjunction with NFC?
Apple is so successful because everything works really well. The benefit of not having it activated from the beginning is that you wouldn't ever feel like it is a half-assed feature like you often find in Android and WP. It would allow time for Apple to make it much more useable.
you think thefts of iOS devices are high now.

There is no reason for it not to have NFC
