I plan to travel to MEM - MXP in October and booking prices are reasonable at the moment. I am seeing $747 in basic economy and $947 in main. Since I am Platinum and have an AA credit card, most of the restrictions for basic are overridden by my status (paying for bags, boarding group number, etc). However, I have no idea if the amount of LP I earn would be different, apart from the obvious difference in the ticket price.

Are there any downsides in booking basic vs main for flyers with higher status?

Thanks!
