Hello, I had an avios booking from Manchester - Heathrow - Tokyo and return all in business for February.

It's been cancelled and rebooked by BA. My Outbound is now Manchester to Helsinki in economy on Finnair, then Helsinki to Tokyo on JAL in business. The return is Tokyo to Heathrow on JAL in business, then Heathrow to Manchester in economy.

Does anyone know why my short haul is in economy? If I call BA will they move these to business? Also do I have any rights to move these flights to alternative dates (they were booked in April)? Thanks for any assistance
