Combining 2 programs
 

Hi,

I am currently *A with OZ while being based at NYC.
When the mileage was 100% at UA, I often reached *A Gold in a year with 60K (Asiana having 40K in 2 years as the requirement). The status was then valid for the current period + the next period, i.e. roughly 3 years.

Basically out of 4 years, I spend 2 years reaching the status.

I was wondering if for the other 2 years, I could switch to UA to try to get more miles as those are company paid travels paid in economy within the US and Canada (but for that, I use AC).

In this case, while I am gathering miles with UA, could I still use OZ card for premier access and lounge? Or is that "impossible" since the premier access is determined by the frequent flyer program used during the booking?

I am not even sure what I am trying to do is really useful or practical. Furthermore, with the new miles table, most UA flights are 50% or 75%, meaning I could require up to 6 more months to reach the status now.

What are your thoughts on this? Does that make sense to try?

yes

Make sure you are not confusing earning rules. There are different rules for RDMs (award miles) from the rules for PQMs (status miles)

When flying UA operated flights, PQMs paid flights credit to UA MP are at least 100%.
When flying OZ operated flights, PQMs paid flights creditto UA MP are at least 70% (G, T, V, W) and all the rest are 100%.

As far as RDMs, the G, T, V, W fares on OZ operated flights are 50% and K, Q, S fares are 75% -- but this is RDMs not PQMs.
