am I within my rights to ask TG to fly me to DXB on another airline?

I actually have plans to go to DXB anyway sometime late march and i am thinking of ways to turn this to my advantage.

perhaps allowing me to cancel and refund a much later flight to DXB (also with TG) and just use the rebooked IKA BKK (now DXB BKK) to leave DXB.
