SYD-SIN in Y, SIN-LHR in J using Companion Voucher
Outbound to SYD already booked in J. SIN-LHR is wide open in J but SYD-SIN only showing Y which is fine as it’s an 8 hour day flight, but is it bookable without splitting the legs and using more Avios?
Im using an Amex voucher so I know it’s only possible to book on the phone, which will be a challenge given the strain the call centres are under at the moment.
