DubiousKB,
As long as you have a ride pre-arranged it's normally not a problem as long as the squad you arranged with has room within their min/max numbers. Walk-on referres more to not having a ride, and just showing up and asking for one.

Yep. There's a difference between "I'm waiting for the invite from VF-17", versus "Hai guyz in teh arenaz, haz any1 gotz teh room 4 me?"
If you don't find an offer, you can fly an SBD with me and the 325th Checkertails tonight. I'm the Bouncer this month, so will be in there tonight somewhere around T-30. What's your in-game handle?
