I am planing to travel  Nepal  in May 2013  and my passport is going to expire in October 2013. So there will be less than 6 month left in passort when I fly to Nepal. I heard that you can't fly if your passport validity is less than 6 month. I don't see any reason for that as I am flying to Nepal and once I am there I will get the new passport when I fly back to US. Please let me know if anyone knoew more about this.
