There's a longstanding rumor that babies born on planes are automatically granted free flights for life, but it's actually a rare occurrence and far from standard practice. Not in this case, though. Jet Airways even posted a congratulatory birth announcement acknowledging the gift (and thanking the cabin crew involved) from its official Twitter account.
For privacy reasons, neither the baby's name nor nationality have been mentioned by the airline, but hopefully he'll have plenty of reason to be traveling throughout India, the Middle East, and Europe, where Jet Airways primarily flies. It's also unclear what place of birth will eventually show up on his passport, since people who're born midair on international flights have long encountered complicated nationality issues.
