This board by cost idea is a joke. typical BA or any Brit company that comes up with an idea to try and gaina few more pounds (on next trip not current one)
However BA cannot manage the boarding process as it is and this will cause endless trouble as how do customers know where they are in the queue.
Easy jet is pretty straightforward here and BA will lose more customers to the big Orange over this.
I have always liked and supported BA but they are a disaster now , I just read an online trip report by an young frequent flyer and he just shredded BA Business Class on an A380 trip, terrible food , terrible attitude , terrible seats and bed, too cramped and crowded which has made my my up that for my anniversary trip wifey will get treated to QR or similar
Shame but you employ monkeys like Cruz and you get a second rate airline
