Just curious if regional airlines are paying for at least space available tickets for applicants these days?
I'm just getting ready to send out some appy's.

If they want you there, they will get you there.

Yes, the regional airlines are providing positive space to the interview. Some airlines are doing phone only interviews.

they all PS you there, and one i know of pays for the hotel

Be advised, once you are flying the line, getting to work (if you commute) is all on you. The company generally will not help you if you miss a commute, and they won't pay for a hotel room, you'll be paying out of pocket if you don't have a crash pad.

Another caveat, if for whatever reason you're not in the US. Like working an overseas contract they won't pay for your ticket in most cases. You'll at least have to find your own way back into the country somewhere.

What airlines are phone-only?

Mesa airlines.

Air Wisconsin offers to fly you standby. No positive space or hotel with them.
