if you read in terms and agreements / contract of carriage, the airline (any airline) has the right to change equip. Which means they went from a larger a/c to a smaller a/c. Or vice versa. Seating arrangements are different on different types of planes. Lets just say you had seats 11abc, now on a different plane 11abc are emergency exit rows. They will not preseat anyone in those seats. People, you need to remember, when you purchase airline tickets you are purchasing "a seat or seats" not a specific seat #! Get to the airport early enough, they all have blocked seating....first come first served. I work ticket counter and always preflight as much as possible. I block seats ahead of time when I know there are families not seated together. However, first come first served. If you show up 45 min prior with a family of 6 not seated together. Well, then I guess it sucks to be you. If I can accomodate you great, however no agent is going to start rearranging people at the gate at boarding time. If it is that important to you to be seated together, get there early.
