Hello experts,

I was wondering if anybody had any experience in switching seats with your co traveller between Y and J.
The story is: I will travel with my mother and because I want to qualify faster for elite I want to book a J seat for me and Y for her. I would like to let her enjoy her first time in business for a really long flight ( aprox 15 hours).

Do flight attendants at TK have understanding for such a switch.Will they allow it ? ( obviously leaving her in J for the complete flight).

Thanks.
