Agree with airline for a very small fee
Who pays this very small fee? The airport pays the airline to accept shop purchases?
No entiendo nada.
Just force the airlines
* to let the passengers make purchases and bring them on board for free like before or like it is with other airlines... That's the best way airports can make money out of the shops.
* The EU should modify the
existing duty-free-shopping law to stipulate that airlines are obliged to allow passengers transport goods purchased airside for free.
