SpiceJet is known to be the airline that does have some fun on Holi, even if this means they get a whack from the regulator.
This year, they did play a safe Holi, by making it happen on the ground rather than in the air. The enthusiastic crew of Spicejet got a wider space to dance to Holi tunes, at the Delhi Airport a couple of days ago. Here is the video:
I assume since they have not heard back from the regulator yet, they must have done fine with the regulations this year. I hope you all had a safe Holi as well.
