Alcoholic drinks provided (and generously so) on my very recents from London City to Belfast and back, together with a selection of crisps or brownie. Slightly different snack oh the way back - Taytos, so clearly catered from the other end.
I’ve seen this before on Cityflyer - people assume drinks are chargeable, despite the announcement of a snack and drink from the bar, so don’t order anything when the trolley comes by.
Then someone in the know orders something, people around them see this and realise it’s a free bar… then suddenly people are ordering wine, G&Ts etc as the service progresses through the cabin.
With the Lufthansa group moving to BOB in economy, BA Cityflyer one of the last remaining fully complimentary services in Europe in economy. Definitely a rare thing in the UK.
