Remember La Compagnie, the French airline that only offers business class seats? We highlighted a great summer promotion from the airline earlier this year -- and it's back again with even better prices for fall. For a limited time, you can fly round-trip, non-stop between New York and London for $2,500 for two (that's $1,250 each) or for $1,500 solo.
It is worth noting that travelers will leave from Newark International Airport and land at London's smaller Luton Airport (not Heathrow) -- around 35 miles from the city center. It's easy to get to the city center from there, though. Among other options, there's a 10-minute shuttle ride to the rail station, which is a 20-minute ride from central London. Considering the airfare savings, the roughly $40 per person rail costs will still let you come out ahead.
