Going home???

I have booked 2 flights….


1. Emirates :

Or


2 Qatar Airways

DOH – KUL 27 Dec 2335 ETA 1155 28 Dec
KUL – DOH 08 Jan 0735 ETA 1035 08 Jan
QR3,330

Hmmm…. Beza…

1. QR 580 (approximate RM600?),
2. time to spend in M'sia… approximately 15 hours
3. I can accumulate approximately 7k Q-miles if i take QR, collecting 20k pts can fly me to London for free... 25k if i wanna go to Madrid. I dont have EK frequent flyer membership.

Which one should I choose… ???
