WHAT???? When did this happen? We got all 4 legs (going & coming home) changed to the exit rows at the 24 hour mark with no extra charges. In fact, Tuesday was the first time we were able to check in on line from Mexico (on Monday morning.) We always used to get a message that we couldn't check in on-line on the Mexico end.
I checked in online this morning right inside the 24 hour mark and they wanted to charge for the exit row seats now. Tried again later today and it said no seat changes were allowed now that I was checked in and flight was leaving within 24 hrs. Major bummer.
