EU banned list
I understand that if an airline is on the 'banned from the EU' list, then safety is likely to be a bit dubious.
However, in some parts of the world, one can either choose to fly with such an airline, or go by land. If going by land is not viable (e.g. roads are in a very bad shape or an area of land between the 2 airports has armed bandits), then one is left with flying, and the need to get a ticket issued. I'm ignoring cases when a banned airline contracts out the operation of a flight to a permitted airline.
Could someone tell me what a travel agent in the UK is (or isn't) allowed to do with such an airline ? Is there a complete ban on issuing tickets for that airline, or is it a case that a travel agent can issue the ticket, provided that they can prove they've told me that the airline is on the banned list ?
