Hey guys!

Quick question. Let's say I wanted to book Doha-LA and LA-DXB. EK J is much cheaper if I book a return to LA from Doha (through DXB rather than 2 separate flights). Are there any rules against going on the LA-DXB flight and skipping the final leg (DXB-Doha)? Are there any repercussions?

Also can I tell the person at check-in in LA to only send my bags to DXB "so I can give something to a friend who's going to be in the airport"?

Thanks!
