Not exactly, I never said anything about switching with people who paid for EBCI. I'm sure most of the people on the flight won't have paid for it.
No, you're right -- but I don't really care where we sit. Basically, I don't care if we have the least desirable seats on the whole plane (all the way in the back or wherever the least desirable seats may be) as long as it's two together (would actually prefer window and middle, not aisle). Also, part of my reasoning was is that we have many flights from my city to MCO every day (even several direct flights), so I don't really think the flight down would be at capacity where I'd have this problem to get just two seats together if checking in right on the 24 hour mark, but you never know.
Just thinking it through since I see so many other people comment on these types of threads that they don't find it worth it and never have trouble with finding two seats together if they check in right at 24 hours. I hate to throw away money if not necessary, but if most people said I shouldn't take the chance, I have no problem spending the extra money. So, that's what I'm looking for -- feedback based on experience.
