You can get a very good rate to go to nepal from Peaceland travels. However, to go to any other destination, I got cheaper rate through other local travel agents. Since there are tons of airlines flying to Portugal, I would suggest looking for an airticket through orbitz. I have found orbitz to be cheaper than expedia for international travels. Although, they charge $10 per ticket as a booking fee for international travels, sometimes it is totally worth it. If you are going to have a paper ticket, orbitz charges about $20 to mail your ticket via Fedex. You can also try sidestep.com to compare the best deals too.
