Some British Muslims have been unable to board a flight because of problems with a new Saudi registration system.
The Council of British Hajjis said that a group of people were told they couldn't fly on a Saudia plane at Manchester Airport on Saturday due to e-tickets not being issued in time.

The allocation of Hajj visas to the UK is not clear. The figures ranged from 3000 to 12,000.

They don't seem to have the capacity to deliver and their technical system has let them down badly.
People were turning up at airports and being told they couldn't travel.
Some people are concerned that their booking may not be fulfilled.
