Haj Phase one (From Indonesia) ended mid January then the actual pilgrimage took place (10 days).
Once it is over, Phase two starts and the pilrgims make their way home.
If my memory serves me right, last year about 200 000 Indonesian went to Mecca. The largest community I believe.
Once the Haj flights are over, you will hear the non Indonesian accents a few more days as ferry flights back to homebase take place.
