I don’t know if this is a normal problem or not, but last Monday at 09:00 I queued for 1 hour to ‘drop’ my check-in luggage at the Aer Lingus desk in Heathrow terminal 1. They had two girls on the desk, one looking after flights to Dublin and one to other destinations. The queue stretched back to the end of the shops when I joined it. Every so often a guy would run up the queue shouting ‘Shannon’ and would drag those flying to Shannon out of one queue and into another. There were no signs saying which queue was for Dublin and which wasn’t. Then the girl checking in the Dublin flights disappeared and the guy had to take over and operate the check-in, so no-one was controlling the queue. By the time I’d dropped my bag the queue stretched right back to the elevators at the end of the terminal. I don’t know if this is normal or not, but if you are checking in baggage with Aer Lingus at Heathrow you might wish to allow sufficient time to do this.
