I've got a Manchester to Kuala Lumpur flight booked 5th Feb coming back 16th Feb...due to work matters I've now got to work in China and come back on the 25th Feb.

I've tried to move my date from the 16th to the 25th Feb still coming back from Kuala Lumpur but they've told me it's £150 to change date....and then over £700 to cover the flight difference (it's economy)

They can give me a later date for just the £150 change fee and no extra cost but the date isn't suitable so I'm looking at flying back from Hong Kong....the travel agents who booked the ticket (through a work company) told me that you can't change the city you fly back from only the date....

Does anyone have any advice on this?
i.e. with emirates can you change the return flight from one city to another?
Any advice much appreciated!
