1st, It doesnt matter if you have 1 point or 10,000, It matter your status
2nd, Depends on who fly in the same flight, If you are the only Matmid,
and the flight is overbooked, you might be upgraded...
I have seen people which are not matmid upgraded to business due to
overbooking and the fact now one left to upgrade.
