Forgive me, I didn't think for a second that anyone was at risk. I was just intrigued as to how Gatwick and Ryanair ended up looking so unprofessional
Lets see passenger has valid boarding card for wrong day and security fail to pick it up right through the system so wondering why Ryanair are being blamed.
The 1st time a FR rep see it is when boarding and it states correct name, correct flight number.
They didn't look at the date BUT to be fair as all the Gatwick checks have already taken place then you unlikely to be looking at the date.
