I flew BF IAH-HNL-IAH on a D class ticket and the fare bonus miles appeared only for the return, but not the outbound. (I paid $200 to upgrade an H ticket to D since mileage upgrade wasn't available) On the OP page, it showed the following:

7/3/01 Air CONTINENTAL 0002 D
HNL IAH 3917
SILVER ELITE BONUS 1958
FARE BONUS 1958 7833

6/27/01 Air CONTINENTAL 0073 XD
IAH HNL 3917
SILVER ELITE BONUS 1958 5875

Is there a difference between D and XD after the respective flight number? Is that why the fare bonus doesn't show up for 73? I would think I should get the fare bonus for both ways... Thanks in advance!
