Commuting for an airline can be very stressful. You seem to spend your life waiting in queues at check-in, passport and security, along with the general scrum and cramped seating - unless you can travel in business.
Add to that you really need a plan B if your flight is full or tech, or the Wx closes in, so your 6 or 4 G days can be eaten into.
The OP says only for a short while, and I would urge that they stick to that for their own health, both mental and physical.
I did it for about a year - but not for a ME carrier - and only short-haul Heathrow to Toulouse. And that was on our own service, so I had free parking at Toulouse and free flights. I positioned in uniform so I could always use the jump seat in those days, since I knew all the other flight crews in the Toulouse base and they knew me.
Even so, there were some anxious moments at Heathrow waiting with a group of other standbys to be called forward - although I was almost guaranteed a place because I could use the jump-seat.
Just FWIW.
