MyTravel is owned by Airtours, so dispite what happens to MyTravel, the same routes should technically be operated, because there is a demand for the routes that pretty much only MyTravel Flies from Manchester.
This could be done with a different airline operating MyTravel, It's really all down to interest in both the airline, and it's routes.
I thought Finnair was going to take over it, as they ran the Rimini flight for a number of weeks in September 04'. Personally I think that if an airline such as this were to take over MYT it wouldn't have as many problems as it does today.
