Other European Frequent Flyer Programs - Vueling GO

Anybody have any experience with Vueling "Go"?

I purchased a vueling ticket through a 3rd party and it shows on my reservation that I have "Go" (there is a big GO! logo on the boarding pass). Also on the boarding pass it says "Information on the airfare: FLEX, XBAG, ASVC"
What do these mean? Do I have a checked bag included in my fare?

Also according to the GO benefits I can do same day flight changes for no fee?? Not even a fare difference?? Right now I'm leaving on a 7AM flight so could I make a change 24 hours before that?

Same Day means exactly that - on the same day. You can change your travel time to any other time on the same day.

Note that you also have to give at least 2 hours notice (before your original flight leaves) so I presume this means you could request the change the day before - but travel can only occur on the same day as you had originally intended to travel. If you are also allowed only to make changes on the day of travel, getting in touch with Vueling before 5am (2 hours ahead of your 7am flight) might be tricky.
