I checked their website earlier this week and flights were bookable for 12, 19, 22, 26 & 29 November and on 10 days in December. I don't know why yesterday's flight was cancelled but all the above dates are still bookable this morning. I'm sure it's only a matter of time though before the SEN-BRN route ceases but that's hardly a surprise with Skywork from LCY now offering a double daily service.
