AApologists are out in full force today. Ridiculous.
I once took an $800 VDB voucher out of business class from BOS-LHR because a Mass school had a large group on board going to London during school vacation week. I ended up taking the bus over to terminal E to catch a flight on BA in Club World which left two hours later. I was quite happy to help out (frantic GA, nervous chaperone, and the lucky kid who got my business class seat). Gate agent had to IDB 4 people even with two volunteers...the IDBs got around $1200 in cash each. There is no reason why this gate agent could not have done the same.
