My girlfriend she got a National Visa "D" for a EU country, as being a family member a parent of EU kid, and it's valid for 3 months.

( she will get a resident card here in my country, they will give it to her as once she will arrive in my country )

I plan for her to get a One-Way ticket with Aeroflot ! but so, I'm affraid, the staff at BKK at the counter will be so ridiculous & stupid and asking a ticket going back to Thailand, before the visa the visa will expire ( on May 2015 ) and they will don't understand that she will be resident in France for a long time..

It's possible maybe they deny to give her a boarding pass, being stupid & think that the visa will expire on May 2015, & she must have a return ticket ?

I ask you that, because I'd also a bad experience with that Aeroflot company ( but it's runned by Thai Airways staff at counter ! )

2 years ago, my girlfriend she got a Tourist Schengen Visa © and then, I buy to her a one-way ticket to EU country, & onward ticket to Turkey ( for proof of exit Schengen states before visa expire ) and you know what ? The staff, denied to give her a boarding pass, they want a ticket back to Thailand !!! they said to her, you're not from Turkey, etc..it's not enough this ownard ticket, so, we have to buy so fast a ticket Emirates counter a cancellable ticket back to Thailand, as they will give her boarding pass.. it's not silly ? and in IATA it's said that Thai people can fly with one way ticket to Turkey, but even I showed them that, they denied !!! they want ticket back to THAILAND !

So, now I'm still so worried, they will make again a stupid things, & pretend that the Visa is expired on May 2015.. and she need to have a ticket back to Thailand !!! and make their own stupid rules..

Ofcourse officially there is no need for a ticket or reservation back to Thailand, and if the airline staff is not stupid they know this. But if you wish to make sure, sent them an e-mail.
