Has to be. The MAN-DXB-MAN July stats over recent years from the CAA:
2014: 66890
2013: 64433
2012: 57691
Outbound pax and not inbound is certainly one possible explanation, but if so, it should have been made clear. Or it may just be inaccurate reporting (68,000 and not 38,000 maybe?
Anyway the CAA provisional stats which should be released next Monday will tell us.
