Aside from F ground service, my experience has been:
- Far better call centre service - I generally have someone on the line within the first 3 rings on every call to the DM no.
- Better availability of full or upgrade seat redemptions on CX flights.
- More frequent op-ups when flights are oversold in the class you're booked in. I value this on short haul flights as company policy is to fly economy under 6 hours.
