Here's a fun little Easter Egg: By entering the airport code for Spaceport America into the "From" field on Kayak.com, and 50m (the number of miles at which the thermosphere starts) into the "To" field, you can uncover flights into space.
Let me explain this to you clearly, since I know you're dying to fork over $200,000 and get anti-gravitational: 1). Enter "90n" (the Spaceport America airport code) into "From," 2). Enter "50m" into "To," 3). Make your departure and arrival days the same, 4). Choose "first" class (naturally), 5). Hit "Search." Voila! You're ready to book! (Granted, you are just booking for now -- space trips have yet to begin.)
Note: Make sure the "m" and "n" are lowercase when you're filling in the "To" and "From" fields.
This isn't the first Easter Egg Kayak.com has busted out with -- last year, the site nestled a flight on Oceanic Flight 815 (of Lost fame) into a search for flights from Sydney’s SYD airport to Los Angeles’s LAX.
"There's a million little tricks on Kayak that are up there because they're geeky," says Robert Birge, the CMO of Kayak.com. "I hope someone books through us," he adds.
