Last weekend I flew from PDL (Azores) to LGW via MAN. Passed through a perfectly thorough and professional security at PDL. On arrival at MAN had to disembark, pass through UK security, and then re-board before outgoing passengers (MAN-LGW-PDL) were allowed to join us on the aircraft. Passport control was not until Gatwick.
Can anyone explain why, since we had been sterile from departure at PDL, we had to disembark and pass through UK security at MAN - is this simply a distrust of Portugese security measures? Outbound passengers joining at MAN were presumably sterile too so where and what is the risk?
Thanks.
