Ok from the PowerPoint that they did display during your introduction when you show up to Doha for housing allowance and plus doing some research to what's the inside story for over a few days, let's talk about what they showed you and then provide you with what's going on.
These possible scenarios (at company discretion). Details are to be provided at the time of joining
1) Fully Furnished Acc at the time of joining
2) Temp Acc for up to 6 weeks then fully furnished company acc
3) Temp Acc for up to 6 weeks then
Capt : 15,000 QAR allowance
FO: 13,000 QAR allowance
As per what's happening to all those that have joined in the last four months, option 1 was given mandatorily. You can opt out but it's a 1-1.5 year waiting period. I know of three four places - Ain Khalid Gate, Al Saad, Pearl, Holiday Village - what are the others, am sure others can fill in which I don't know personally.
