Yes, this is true, but I remain hopefully optimistic about something booked for late October, whilst also having taken steps to mitigate against schedule changes (booking several hours of transfer time between each flight) and cancellations / rescheduling (booking everything directly with BA on the same ticket). Vaccinations continue apace both here in the UK and in the US, and while something like a new variant strain could certainly put paid to current plans, things are looking more hopeful. Who knows - the horse may yet learn to sing!
