For a passenger with ornithophobia - a fear of birds - this experience would be the new Snakes on a Plane.
A plane at Ahmedabad International Airport, India, on Friday had two avian stowaways.
Shortly before the flight left the terminal, the crew found a couple of pigeons in the cabin, The Independent reports.
A video shared on Twitter by India TV journalist Nirny Kapoor shows a fully booked plane and two pigeons flying down the aisle while some attempt to catch the birds with their hands.
An air hostess is also filmed ducking as a pigeon flies overhead.
GoAir has since apologised for the incident.
"GoAir regrets any inconvenience caused to its passengers and requests the airport authorities to get rid of this menace," the airline company said in a statement.
GoAir rejected accusations the birds were loose for half-an-hour, saying the flight left for Jaipur on time.
People have since responded to the video.
"Efficiency! Why flap your own wings when someone else will do the work for you?" wrote one person.
"Wonder why a pigeon would need to board a flight when it can fly for free!" said another.
