Was just looking at submitting an e-MCO against a trip which I've already booked and will be flying in the next few weeks. The trip was originally booked using a public 15% off promo code offered earlier this year. Now when I read on the e-MCO web page it states that "An e-MCO cannot be used in conjunction with a Promotion Code."

Just wondering if this is correct? The MCO is for $500 so I'd hate for it not to be valid based on a technicality. When I received the MCO there was nothing which stated any conditions around promo codes.
