First time traveler, need help understanding the process.

Hey all,

So I booked a flight from Orlando Florida to Bangkok Thailand the other day through BravoFly (I know). I didn't do enough research and only found out how terrible they are after the fact but I am hoping to make the best of it. I have flown many times in the past domestically but never internationally so I am slightly confused and overwhelmed with the process.

The flight is Orlando > San Francisco > Taiwan > Thailand. I received my confirmation email with booking number as well as the PNR number for the trip. The domestic portion is with Alaska Airlines and the other part with EVA Airlines. When I type the PNR number in on the Alaska Airlines website the trip comes up, but when I type it in on the EVA Air website it does not. Is this cause for concern?

Also, do I just get my tickets/boarding passes when I get the the airport or are they sent to me beforehand? Will I get the tickets for all 3 legs in the beginning or will they be given to me separately during the layovers?

After hearing the negative reviews of BravoFly, I am worried that I will be missing something. I apologize for the basic questions but any help will be appreciated.
