Well, the official BA document I linked to has these three categories:
1. Flight Withdrawals from 25 October 2009
London Gatwick to Alicante
London Gatwick to Krakow
London Gatwick to Malta
London Gatwick to Palma
London City to Lyon
London City to Barcelona
2. Cancellations for Winter 2009, from 25 October 2009 (The service will resume for Summer 2010.)
London Gatwick to Varna
3. Cancellations for Summer 2010.
London Gatwick to Ibiza
If it was to resume in summer 2010, would the route not be listed in the section of flights resuming in summer 2010?
