For the interview, they've requested us to bring letters of recommendation. I don't currently know anyone at Frontier, so would a general letter of recommendation, or maybe even past recommendations referring to me as an employee suffice?
Also, I've been running with an electronic logbook for some time now. Signatures from all previous DPEs are requested for all check rides we've done. Would our PRIA be what they're looking for in this regard, or have people been tracking down their past DPEs and getting copies from them or the FSDO?

Thanks guys.
