sorry if this has been answered already, but if i buy 2 roundtrip tickets for myself and spouse, and from what i can tell, purchase the EMS seats for us separately maybe a day later, (or a few hours later), theoretically i would receive the credit for the EMS seats, right? also if i pay to check bags at the JFK b6 kiosks, possibly that can be credited too? thank you, newbie here, applying for the card soon, figured to do some research first...
