Just wanted to ask a question regarding a return journey ticket from Toronto to Heathrow in December. My mom is coming from Toronto and then going on to Singapore. Initially she had no plans to stop over in London but now she wants to.
Whenever I have tried to look for a one way ticket it seems to cost much more (nearly double) as compared to a return ticket in the same route.
My main question was - will it be illegal on my part to get a return ticket and use only one side of the ticket? Second question I have just noticed if I were to buy a ticket going Heathrow to Toronto and return - then the tickets are slightly cheaper as compared to the other way round. Now if I buy the ticket and no one actually goes from London to Toronto but my mom uses the return ticket - is there anyway she can be stopped in toronto and her ticket invalidated?
Any help would be really appreciated and reps added.
Thanks in advance.
