I booked a work trip to LIS for a few days early next month.

My daughter decided that she wanted to come too so the next day I booked her a ticket using my Avios.

When making the booking I couldn't book her a child ticket (she's 14) as it would appear that she's travelling on her own, even though she's not, so I just booked her an adult ticket.

Does anyone know if this could present a problem?

TIA dahlings.
