Trendcentral says:

"Airtroductions gives users the opportunity to connect with others of their
choosing for air travel. Whether professional or personal, users create a
profile which is posted on the site. After entering an itinerary, users are then
notified when others are booked on their same flight. Given the option to send
an anonymous email, flyers can try to meet up before the flight and even try to
sit next to each other."

Does this make sense?
