Not sure is anyone can help...
But just read on the Olympic Holidays Facebook page that the tour operator has stopped using Strategic Airlines with immediate effect for all of its charters...
It doesn't state a reason why, but this seems highly unusual for them to do this when they are only a few weeks away from when the UK summer holiday programme comes to an end.
I have Google-ed Strategic Airlines and unable to find anything news articles suggesting an incident or that the airline has stopped trading. Also their website is fully up and running.
This is what they posted on Facebook:
IMPORTANT TRAVEL UPDATE
Olympic Holidays regrets to announce that as a result of information provided by Strategic Airlines it has felt compelled to end its flying contract with Strategic and to arrange for the remainder of its summer 2012 flying programme which was to have been carried out by Strategic Airlines, to be provided by other carriers.
These are: Aegean Airlines (which already provides flights for Olympic Holidays); Travel Services (an airline with a growing reputation in the Czech Republic); and an Italian airline Livingston Air. Flight timings are little changed and all clients should proceed to their departure airports as normal and use the tickets that have already been sent to them. Clients departing from London Gatwick will be travelling on a Livingston (flight code JN) flight at the same time and from the same terminal (South) as their original Strategic flight; clients departing from Manchester will be flying with Travel Services (flight code SQ) from the same terminal (2) and at the same time as their original Strategic flight.
We wish to emphasise that any change applies only to clients who have booked travel arrangements which include flights with Strategic Airlines (flight code STU). All other flights are completely unaffected.
