I just checked my CMH-DFW-SFO trip for this fall and noticed that my first leg has moved up by almost 3 hours and my DFW layover is now almost 4 hours. My arrival time is still the same though (but later than what I originally booked due to an earlier schedule change). I hate this new itinerary. Any chance of getting this changed without extra spend? There doesn't appear to be any AA departures close to my original departure time, but at the very least I'd prefer to get on an earlier DFW-SFO flight to shorten the layover.
Of course, just research whatever new flights work the best, then call AA and ask specifically for those.
