The only reasons Economy Comfort exists are as a small token to try to make medallions feel slightly better for not being able to get international upgrades, and to extract additional marginal income for a very minimal alteration in the hard product (in most cases, it's just an adjustment to take advantage of space that's otherwise unused), and a very slightly different seat (headrest wings and an adjustment to the recline limit).
