I agree, that's why I was considering meeting them and flying with them.
The reason for the C1 visa is: EVERY FLIGHT from PTY to PVR transits through some US city, MiA, DFW, SFO, LAX IAH etc....... also, by the crow flies, Puerto Vallarta is 5 hours from Panama City, yet the fastest economy flight duration is 13.5 hours, costs over $6,000 for two economy seats. and still flies though a US city AND Mexico city. obviously it's not a viable option. The least expensive flight is $800, takes over 23 hours and STILL flies through Houston.
