This year, I was thinking about flying enough to qualify for TC Silver.
I have an EZE ticket booked, which would net around 25'000 club miles. I was also planning doing a BSL-GVA-JFK run in February to take advanage of the double miles promotion (and upgrading to C while the old award chart is still valid).This would give me around 9'000 club miles.
My question now: if they don't credit me the EZE miles (as discussed on FT), I won't have enough activity to reach 40'000. Should I risk it and still do the run to New York ?
Is Travelclub Silver worth the risk ?
