Servisair at NCL always have vacancies for dispatchers, and despite looking to fill temporary vacancies, they always end up permanent (if they stay that long). The temporary thing is simply so that they can pay you terrible wages for 6 months, then try and con you into accepting an extension to your temporary contract by saying you have failed to perform satisfactorily. It's much more common in passenger handling than dispatch as we're not quite that dumb (close, but not quite).
Check-in is a terrible job, especially here at NCL, and there is limited movement between the departments. Depending when your 18th birthday is, I would hold out until then and reapply. Once you're permanent, you can expect a mighty £6.25 an hour, but despite the wages, the job is actually quite good fun as long as you can put up with the inability of the station management to address the long-term priorities of the business. It seems that the only management tasks they are capable of is the issuing of memos regarding the use of mobile phones and company dress standards. Staff shortages, broken equipment, lack of training, ineffective rosters and persistent short-term absences are all far less important and therefore do not warrant the necessary attention required to interrupt the latest coffee break.
