Self-reporter here:
Yesterday's BA893 check-in situation from SOF was a mess. 3 of the 4 counters had opened with CE in the middle and naturally not adhered to and impossible to access unless you were already in the long line. A braver CE/DYKWIA individual approached the 4th agent who just sat down at a new check in counter (still closed) to which she said "just check in at me". Me and the wife then proceeded to the horror of ~200 people in line (and Mister
Greenpen himself if im not mistaken) to skip from the end to the newly opened counter. A lad queueing behind me started asking "Is this...." to which I promptly replied "this line is for
business class" to which he responded "Oh sorry!" and rejoined the normal queue.
To confuse matters even more, after us the 4th counter we had just used opened as "Euro Traveller"
