What you can try is to visit the website of Saudia, then click, 'manage my booking', choose 'e-ticket' and fill out the required information. If the ticket is issued, this site will most likely show it: it shows a lot of e-tickets, also outside SkyTeam. I've used it a few time to look up booking class on certain tickets.

Not 100% sure if air Moldova can be found here, but it's worth a shot. And credit to Oliver2002 for showing me this possibility.
