JetBlue is offering a last-minute holiday bargain on business-class travel between New York City and London in early 2024. You can book a round-trip business-class seat right now for only $1,835. And by right now, we mean right now — the offer expires at the end of the day Dec. 20.

Business-class seats for this incredibly popular route typically cost at least $2,500, so this is a fairly significant savings. Keep in mind this applies to travel between New York’s John F. Kennedy International Airport (JFK) and London Gatwick Airport (LGW). A Saturday night stay is required to get the discounted price.

Gary Leff at View From the Wing was the first to spot this deal.

How to book: Visit JetBlue’s website and book directly through the airline. Be sure to enter your TrueBlue rewards program number.

Travel dates: The sale price is for travel between January and March 31, 2024. This means outbound travel must begin by March 31.

Book by: Dec. 20.

We found this price available in all three months that the sale applies to. Here’s one example from JFK to LGW in late January for just $1,835. Keep in mind this is for JetBlue’s Mint business-class product, which features lie-flat seats, direct aisle access, large TV screens and, of course, food.

We found the most availability for the sale price in February, including this one.
