Already thinking ahead to Thanksgiving plans? Depending on where (and when) you're traveling, it's sometimes cheaper to fly international than it is domestic. Searching Norwegian, we found seats for $381 nonstop, departing Chicago on Wednesday, November 21, returning from LGW on Friday, November 30.

You'll find slightly lower fares ($371) available for non-holiday travel in October/November.

Passengers are allowed one carry on bag weighing no more than 22lbs. The fee for one checked bag is $45 each way. Nowergian's LowFare+ option for these dates is $561 roundtrip and includes both carry-on and checked baggage, seat selection, and meals.
