Goldtrail still use OHY from NCL, as do Holidays4U, however not as much as in previous seasons, with Turkuaz, Saga and now Sky Airlines being utilised. Companies will tender out their business in charter land regularly and money is huge factor when contracts are awarded. You only need to look at the likes of Thomson Holidays and Thomas Cook Tour Operations, where in recent years their flying has been brought mostly in house, as opposed to using the llikes of Air Europa, Spanair etc.
