Having returned from base camp the previous day, we were eager to continue our journey on to Laos but had to wait for money to clear to pay for flights. That morning, as soon as the funds were in our account, we jumped onto the airline website to book our flights out of Kathmandu for that afternoon. This turned out to not be possible via the Internet if booked within 6 hours of a flight, leaving us with the option of staying another day or finding an alternate way to book.
