As a Us citizen living and working in the UK I am required to hold a Resldence Permit (RP) from The UK Home Office. On ** Sep ** my wife and I checked in at Terminal * for flight BA *** from LHR to Boston USA. *Upon booking the flight I requested special assistant as my wife has a mobility problem and needed wheel chair assistance all the way to the aircraft door. This was granted and a BA staff member named Victoria (Vicky) stayed with us throughout the ordeal. She was very helpful and passed and received back our boarding passes and documents at the various check points. Vicky was instrumental in getting us to the aircraft in time to board as it was a very hectic rushed experience.*It was only after take off that I discovered my RP was missing and must have been misplaced during the checks. *RPs are printed on a Biometric card about * by * inches in size and sealed in plastic having my name, photo, and RP number (RJ*******) on it.*I would appreciate you checking if it had been turned into your lost and found department or returned to the Home Office. My home land line number is *********** if you would like to ring me regarding thi matter. I look forward to hearing from you. Sincerely Richard James Waldo.
