En-Route
I also had a multi-month wait for my PPL. Spoke with three different DPEs in Oklahoma and couldn't get them to even give me a date or date range for my exam. I even had my CFI call. They literally wouldn't call me back with a date, give me timeframe of when their schedule would be more open, and when I got a response from 1 of the 3 it was "July" when I was asking in early May.... Finally got fed up and starting calling DPEs is neighboring states and found a great DPE in Arkansas which required a 2hr cross-country flight to my exam but he got me scheduled within one week of our first phone call and I passed. I'll probably just call him for my IFR and not bother with the Oklahoma DPEs.
Yet the FAA receives very few complaints.
Nothing will change unless people submit complaints.
