Self Check-in Machines
I came through CDG 2B for BA flight to BHX this morning for first time in about 12 months. BA seems to be relying almost exclusively on the machines now rather than traditional desks. A row of about 10 or 12 machines was monitored by one (very nice) BA lady with one other on a single ticket/enquiry desk nearby. Guess you can also check-in traditionally at the gate (one very bored lass at gate B33 check-in desk) but as the Gendarmes aren't inclined to let you through passport control without a boarding card, I'm not sure how the system copes with pax's who can't or won't use the machines.
Personally I like the machines & use them whenever I can particularly as they allow you to beat the normal check-in queues such as the Swiss desks @ Zurich, which seem to have perpetually long, slow queues.
