An adorable video from Newsflare's library of an entire plane singing happy birthday to a four-year-old girl on board a Southwest Airlines flight over the US.

The footage, shot earlier this month, shows a flight attendant announcing to the passengers that a little girl called Mazzy is turning four - asking them to lower their window shades and start singing.

Their mum later said online that Mazzy's big sister asked for the special announcement: "Her big sister demanded we tell the flight attendant in hopes of getting her some wings! They far surpassed all of our expectations

"Mazzy has Spina Bifida leaving her paralyzed from the chest down. Traveling isn't easy. Can't thank southwest enough, not only for the most unforgettable birthday but for making our difficult traveling situation so much easier".
