It is not a case of RYR 'giving up' routes but the Italians telling them to sod off, and good on em for doing it. In UK any other airline on domestics will accept official photo ID (WTF did Gozo get fishing licence and blockbuster card from?) in the form of driving licence, ID card etc, but it must have been issued by a recognised authority. Perhaps it is because RYR want to employ the lowest form of staff at the lowest wage and dont want to confuse the poor bozos.
