There are some people with no family in Qatar so many enjoy a 10 day trip to N/S America vs staying here. Others hate it.
In general I would say an average month is 4-5 pax flights and 1 cargo trip...often a short trip like Frankfurt or Hong Kong and back following day.
They usually send you on a longer 5-11 day trip every 3rd month.....although as the cargo division grows it is becoming more frequent.
