A comparable challenge is those with two names.
Mrs WHBM
is from Russia, married to Mr WHBM
who is a Brit. Now she has two passports, British and Russian. Russian one has original name, British one has British married name.
So when we buy a round trip ticket between UK and Russia, what do you think the procedure is ?
Book ticket in UK name. In that case need to show UK passport on leaving UK and they will want to see entry visa for Russia. Russian consulate will not give a visa to someone who is already one of their citizens. No visa in a UK passport, no departure. Show Russian passport, but this of course has different name.
Book ticket in Russian name. OK on the outward trip. But coming home the reverse now applies. No UK visa in Russian passport. Show UK passport, rejected as has different name.
Immigration officers are fine at both ends with showing the "home" passport, it is just airlines that cause the issue.
The whole thing would be readily solved by airline reservations having an extra field for "also known as", to handle people with two names, as here. It is a common issue that carriers have completely ignored - and the whole palaver has NOTHING to do with security.
Anyone from airline procedures care to comment ?
