I was wondering if it possible to book an empty seat on Cathay Pacific flights?
I mostly travel in PY, but recent CX PY fares ex UK are double Y.

I would be travelling with someone else.
Has anyone tried to book an empty seat? for example 2 people using 3 spaces.
Can we collect the miles and use the luggage allowance?
Discount on ticket price? (since its an empty seat 80kg less and tax)

Would 2 people sharing 3 Y seats be more comfortable then 2 PY seats?

Did a random day search on Kayak
LHR-HKG 8th May- 22nd May
677GBP Y
1331GBP PY

2xPY= 2662
3xY= 2031

Would welcome any opinion and ideas

Thanks in advance
