Same for me. The flight must depart the USA and be transatlantic but no need to end in London. I have consistently had to request the bonus from Chase though, it almost always fails to post automatically, and in fact I submitted another such claim this week. If it is a one way flight, or a return comprised of two one ways, I think it frequently fails to post automatically. Send a secure message, they will almost certainly send back a canned email telling you what the conditions are then asking you for the booking reference, flight class, dates and amounts that the taxes/fees were charged to your card. Even if you send this information in the original request it seems that they have to ask you through the process of sending the pre canned response, and then about 5 days after you reply to that with the required information, they agree that the bonus should have been paid and then they make it happen. I use the heading Account Inquiry because if you choose card benefits they simply refer you to some web pages.
