Extra flight availability? Likely or no?

[mulv2222]

Apologies for the recent flurry of questions from me….

There is availability to fly to SIN for our dates, but no return – this is in September this year. We need 4 flights and only 1 is available. We have 2 x companion vouchers to use. Is it possible that more flights might become available if I book one way? If I book another return airport ( and get a one-way flight there), how easy is it to change if something comes up?

I presume for a companion voucher, I still need 2 seats to be available and not just 1?

Thanks again for your help with this!

I think some of this info is on your original thread:

You do need availability for the companion as well as the voucher holder. If any extra seats become available, you can change your booking for £35 pp.
