Can you book a stopover when booking a flight on Avios.com ?
Wanting to book MAN-LHR-TXL as a reward flight saver. Zero availability on BA.com but Avios.com has plenty of availability.
I'm wanting to fly MAN-LHR on day 1 then onwards to TXL on day 2. But I don't seem to get offered the stopover option on Avios.com like you do when booking via BA.
