Hi,

I recently done 4 flights on Delta's Business/First (BCN-ATL-SAN-ATL-BCN) on I&F reservation class. While after 10 days only the SAN-ATL has been credited to my FB account, I've discovered this morning only were credited the 100% of the miles route. After checking the miles table I've seen should be 150% for I&F classes so don't kwow wy only received the 100%

Any idea what to do? Call to FB Service Center? Write a letter to Customer Center?

Thanks!
Xavi
