May not be January after all, but flights up to the New Year are the only ones 'guaranteed' so far.
From the statement.
Flights to and from East Midlands up to the end of 2009, including the Christmas and New Year period, are wholly unaffected. Passengers do not need to take any further action and their flight will be operated as planned. Passengers travelling after this period will be informed well in advance if and how their travel might be affected.
