Hi friends,

I have a return ticket booked on MEL-DEL-MEL with Singapore Airlines with stopover at SIN in both directions.
However, the layover in SIN in MEL-DEL sector is 17 hours. I took the ticket as I was planning sightseeing in SIN. However, now I have no plans to take along halt there. Can i go to SQ airline agents in SIN and ask them to put me in an earlier flight if seats are available. If yes, will it affect my DEL-MEL tickets, because, as i understand, if i donot show up on any leg of a return ticket, the subsequent tickets are cancelled by the airline.

Also, i booked in Economy Flexi fare, is there a chance that they can put me on an earlier flight without a charge.
