Ah yes, you're the lucky man who got his gf cooking all those delicious recipes up, making NT'ers like me Jelly, haha.
But for the serious response. I've never dated a flight attendant before but I've had enough LDR experience under my belt to understand where you're coming from. First off, from your story she just got her certification to become a flight attendant. Meaning she invested so much time, money and effort to get to where she's financially stable, which is a good thing. However, which you are already aware the timing for her availability can vary depending on how busy her airline could be and etc.
Now I'm not one to pry or assume out of relationships but it looks like she's treating you good and hasn't given you a reason (or motivation rather) to leave. So you can also be sure she's probably open to working things out. And as some people have already implied it's only 1 YEAR and despite your lack of seeing her, if you want to make things work you gotta compromise and be ready in all aspects (emotionally, physically and etc.) to deal with the lack of presence your partner may have. On the flipside, it is a lot to ask for in a person given the relationship is fresh and the foundation just started building. I think the first thing you should do despite entertaining NT's interest is to talk to her about how you feel. Don't mention about immediately quitting her job but do tell her that it concerns you and if she's real good (and not heartless) do imply it may cause a rift given the lack of time spent on one another. And besides, it's only 2 MONTHS so... definitely take a bit slow you seem to be getting a little easy on the acceleration paddle there.
If you haven't already established being on the same page and same wavelength of the duration of the relationship... now is the best time. Otherwise, you (or her) will be left dangling in the air and someone's bound to get hurt or misunderstood. Good luck OP.
