Check out this great, cheap flight from New York to London — Just $333 ROUNDTRIP! A good sale for nonstop service to London. Norwegian has some cheap $194 outbound and $223 return tickets on sale for travel from January – March, 2017. This deal is best if you can travel light — 1 bag under 22 lbs. Norwegian is a low cost carrier so they will charge you for everything – advanced seat assignment, luggage and so on. We priced this in British Pound Sterling to save you about $84 (if you were to buy this in USD, its $417 — whereas this is £272 or $333 USD at today’s exchange rate). Use a no foreign transaction credit card to save on the f/x fees. We recommend you prepay for luggage since Norwegian only allow ONE piece of carry-on up to 22 lbs. This fare doesn’t earn any useful miles. The UK has very high taxes and fees, it is very difficult for it to be cheap. A typical roundtrip coach ticket to most airports in the UK has roughly about $215 in taxes and fees.
