I've had the following conversation with at least 5 LAA pilots in the past 6 months:
Me: Hi, I'm Kevin. I'm with American and was hoping to catch a ride with you on your Jumpseat.
LAA captain: Sure, no problem. What fleet are you on?
Me: I'm on the E190 in PHL.
LAA captain: Oh, ok. So are you with Republic? *starts looking at my badge for a regional logo*
Me: No, I'm with American.
LAA captain: yes, but which commuter?
Me: I'm mainline.
LAA pilot: *totally confused* Oh...ummm...ok. Well, I'm sure you'll be at mainline soon, son.
