A big lesson I learned during this past trip to Nepal is "if you are getting the same price, buy the ticket from the airline's website, not from third party or websites like Priceline/Hotwire." I had some issues and whenever I called airline to fix it, they said, "since the ticket is not from us, contact the agent" and the agent was very busy to handle my issue. It was too tedious. If you are getting a better deal from the agent, then go through them. Otherwise, get it through the airline directly.
