If the rescheduled flight gets you to your destination an hour late domestically or two hours late internationally, you are not entitled to any monetary compensation. After that, the window of time varies for how much money you are entitled to. But airlines can owe you up to $1,350 for a one-way ticket, and you can negotiate for more if you feel entitled.
But make sure you show up on time and have a confirmed reservation. Otherwise, you may be entitled to nothing.
