Of the BAL fleet last year, DAGYF was on the Hadj and went to Brunei and GBNYS ferried from/to LTN. YS ferried halfway round the globe because it still worked out something like $1.5million cheaper than going to Monarch!!!
The plan is for all aircraft to be maintained in-house, but I wouldn't be surprised to see one or more of the Hadj aircraft get checked in Brunei again.
