Shopping for regionals here. While EDV clearly leads in the money department, I'm wondering about the flight benefits (which I intend to use a lot).

- Do the benefits apply to SkyTeam partners (e.g. Korean air, Air France, etc)? Do you also get on first/business with partners?
- Can you 'check-in' 24h prior the flight to pretty much guarantee your seat (like it's done with ENY and the AAG), or is there always a chance to get bumped last minute by a mainline guy or someone ranking higher?
