Aer Arran says its working on a revised schedule for flights beteween the Isle of Man and Dublin next week - if its pilots go ahead with a planned strike.
The airline operates daily regional flights between Ronaldsway and the Irish Republic on behalf of Aer Lingus.
In an escalation of a long-running pay dispute, Aer Arran pilots have voted in favour of a walk-out on Tuesday, Wednesday, Saturday and Sunday next week.
Aer Arran bosses say they'll operate as many flights as possible and are due to release details on Friday morning.
Ports Director Ann Reynolds says the route to Dublin is an important one for the business and leisure markets:
