The first day of April sees airlines around the world decide not to take themselves too seriously – with some travel and aviation websites also getting in on the fun.
Here's a rundown of this year's best airline-related April Fool's Day pranks.
Qantas brings Airbus A380 flights to Canberra
Added as extensions or 'tag' legs to Qantas' existing Sydney and Melbourne A380 flights, the capital city's superjumbo service would "give pilots flying the giant Airbus more practice in take-offs and landings" Sandilands wrote. "Qantas partner Emirates has also expressed interest in doing such tag flights as part of the expanding alliance."
"From an operational perspective, the flights will solve the problem that A380s fly such long sectors that pilots do not get sufficient hands on take-off and landing experiences per month, forcing the airlines to invest in costly simulator sessions. Qantas CEO Alan Joyce is reported to have mused that 'training sessions that bring in actual passenger revenue can turn long haul operations profitable...'"
Avoid kids on your flight with Skyscanner's Kid Counter
Meanwhile, travel booking website Skyscanner revealed its latest feature: the ability to predict "the probability of sitting next to a crying baby or seat-kicking child" on your next flight.
Skyscanner boasted that its software relied on "previous booking patterns and travel behaviour of millions of users, along with seat preferences and aircraft layouts".
Here's how things look for flying from Sydney to London on a Monday in June...
Virgin's glass-bottom plane
Richard Branson got into the spirit of things with the announcement of the world’s first glass-bottomed plane.
Set to debut on Virgin's new flights between London and Scotland this "aviation breakthrough which has been years in the making" would allow passengers to appreciate the beauty of the British landscape during their flight.
Virgin America gets dog-friendly
WestJet gets pet-friendly
Not to be out-done, Canadian airline WestJet said its new Furry Family policy would welcome all types of pets in the cabin, provided your pet can fit safely on board the aircraft.
What we love most about this stunt is the effort WestJet went to to shoot this special video introducing the scheme.
Delta's double-decker arm rest
Delta figured it was time for passengers stuck in the middle seat to stop fighting over the armrest.
Behold, the innovative yet "Why didn't somebody think of this sooner?" double-decker armrest!
Southwest expands its fleet with hot air balloons
Forget all that hoopla over Boeing 787s and Airbus A350s. Southwest figured that April 1 was the perfect time to announce its fleet would now include hot air balloons so that travellers could step out of the frantic fast lane and take things slow for a change.
"Enjoy taking it slow with a scenic view while traveling from Boston to Denver" the airline boasted.
"You'll have a full 31 hours of seemingly never-ending ground-peeping, star-gazing, and gusty nap time. Or you could sit back and relax during an estimated six-hour jaunt from Dallas to Houston. (DISCLAIMER: Travel time greatly depends on wind speed)".
