I have been checking fair for march since last couple of weeks. If you you break your jorney from here to london and from london to ktm via middle east then that is the cheapest one through europe. But I am still worried about the transit visa requirement of UK for Nepali. Although there is an exemption for people with USA valid visa and airline tickets I am kind of worried what if some neo-sense people does not let me board in the plane by looking at my Nepali passport. That's why asked about this issue in few days backs posting. I am still looking for answer from people who have transited through London without DATV. If some of you happens to be that person please share experience. Back to ticketing again, BKK route is way more expensive in my finding. Cheapest one is through the Delhi but I am trying to avoid it and reason is quite obvious. By the way all my findings are solely based on orbitz. I could not find any other better website.I have not tried travel agents yet because my dates are not fixed yet. Your past travel experience will be highly appreciated. Thank you for those who have shared their experience so far.
