Full Flight Manchester to London Heathrow Airport British Airways

Travelling after lockdown easement. Flying on British Airways A319 from Manchester Airport to London Heathrow Airport. Boarding the aircraft is straight from back to front and then exiting is done in a few row numbers bit by bit. Right now we get water, crisps & pretzels though I think it will go back to pay on board when certain things have finished. Flight time was around 35 minutes. London Heathrow Airport had only 1 runway in use and is expected to be like that for 3 months.
