It's our first time booking a cruise and we're not used to holidays where we don't know the flight times beforehand. We're thinking of going on the Britannia from Barbados in Dec 2020 and our closest airport is Birmingham. However if the outward flight times are early we'd likely want to stay in a hotel the night before anyway, and could therefore save the £100pp supplement and fly from London instead.
So we are wondering if anyone knows which London airport is used most often by P&O for this flight, and a rough idea of what the departure times might be from either London or Birmingham. Are we looking at 6am, 9am, 11am?
