My 30 August BA238 BOS-LHR flight (the early morning departure) just got cancelled, and looking at ExpertFlyer it looks like that flight has been pulled from the schedule from 25 August to 1 September. Any speculation why? I have a non refundable hotel that night, and at any rate would like to get to the UK earlier. Do you think they'd route via JFK via a connecting flight that departed the previous day?
