Delayed Flight during a pandemic

Boarded my flight by 11:45. Take off was for 12:10. Been sitting in this flight for 40 minutes now in a damn pandemic. Waiting for bags to be put and some bags taken out. Surely Mango can do better than this. Especially during a pandemic! To have people sitting in an aircraft that is completely FULL.. with so little space AND very little air ventilation I'm literally sweating so much and I'm struggling to breathe cos of my mask.

What logic is this???? IT WOULD HAVE MADE MORE SENSE TO LET US WAIT IN THE AIRPORT!!!
