I'm traveling next week. Since the beginning of last week I've been getting a daily copy of my electronic ticket receipt and itinerary. It's a combo B6/HA itinerary issued on an HA ticket.

The e-ticket numbers are the same in all the copies.

There was a minor schedule change on one of the B6 legs between my initial e-ticket receipt when I booked the flights and this set of receipts. But all the recent copies of the receipts are identical in schedule.

Any idea why I'm getting these copies every day?
