I just came back from a trip to Bishop to visit friends, and was randomly surfing the TripAdvisor Bishop page while talking to another friend about airfares. I clicked on the "Flights to Bishop" link, and was surprised to be provided with airfares to Fresno. Fresno isn't the closest airport -- the closest airport by far is Mammoth Yosemite Airport, served by Alaska Airlines. It's 37 miles from there to Bishop, according to MapQuest. If you fly into Fresno, because of the mountains, you have to drive south through Bakersfield and Tehachapi and north again through Lone Pine to get to Bishop -- MapQuest says it's at least a five-hour drive. Even Reno/Tahoe Airport is a quicker way to get to Bishop than flying to Fresno.
