Need some urgent advice.

I have a very lightly used 2020 MacBook Air (8GB/256GB), always kept in a sleeve and in near-perfect condition with no physical damage at all.

After a recent flight with pretty bad turbulence, I opened it the next day and noticed a very thin green vertical line on the display. The laptop was kept in the overhead luggage compartment during the flight.

One more thing — the cabin felt extremely humid and they seemed to be using a lot of humidification. Could moisture/condensation have caused this internally? Or is it more likely display/flex cable damage?

Any idea about probable fixes besides a full screen replacement?
