OK here's my situation. I'm also asking some financial & practical advice.

I'm a flight steward based in klia2. I stay in Taman Desa, Old Klang Road, KL. However, I do only turnaround flights (i.e. to & fro flights, I never get to spend the day/night at the destination). It means I travel up & down from KL to KLIA & back every day. Working hours & off days are not fixed.

Currently I take the bus to klia2 from KL Sentral every day.

Recently my dad has suggested I sell off the car & get a new one to do Grab/Uber on the side.

How feasible is doing airport trips OTW to/from work?
How much can I earn in a situation like this?

This doesn't take into account that I might do trips around KL/Klang Valley during my off days.

Thanks in advance.
