Right so therefore you need a card machine at every desk and ensure that the people at the desk know how to use them, then there will be the people who can't find their cards because its in one of their pockets or rucksacks or they forget the pin or it just doesn't seem to want to work while passengers who comply with the T and Cs stand behind waiting and waiting.
Right, so they will instead stand behind people repacking suitcases when they discover the 15kg weight limit can't be pooled so their toddler's bag must carry more weight. Sorry, the idea that Ryanair's policy on this is to minimise the wait of passengers who "comply with the T and C's" is comical. Let's be honest here: RyanAir's policies are designed to maximise the amount of fees they can extract from passengers to balance out their supposed low fares, whilst at the same time incurring as little cost as possible themselves. They actually
want passengers to turn up with overweight bags and fall foul of other restrictions. That's the whole point.
