I get that and that fare buckets go etc and if it was just one day's fare that had gone up, I wouldn't have bat an eyelid. However, it is all tickets across 10 weeks that have gone up to a fixed amount in the last week. Tickets that are still available at the previous fare rate if you travel from several European destinations with an additional flight in to London. I find it hard to believe that over two months worth of tickets to a single destination four-five months away have simultaneously sold out in under a week after being at the previous price for ages all while miraculously, those tickets are still available for less than they were before but including a third party airline transfer from a European country. Just no way.
