Paying Extra for Comfort+ to do Same Day Change
On the flight I'm looking at, it's about $30 more for comfort+, but the flights I actually want to take are about $100 more. Is there any reason (other than no comfort+ being available day of, which seems unlikely) why I wouldn't book the comfort+ on the cheaper flight? There are multiple options for the flights I want to take, so I'm not too worried about no seats being available. I don't really care about the benefits of comfort+ and have never not gotten it on these flights as an upgrade anyway. Just want to make sure I'm not overlooking something.
