I don't think she traveled for that reason. She was seen catching a flight in LAX the 22, but the 24 was her birthday, she was probably back home for that date. It's possible it was a one day trip, for me it screams work meeting.
Bryan mentioned they were filming shots in New York.
Anna caught the flight right after Comic Con. New York is not Home (she lives in Santa Monica) for Anna, her father lives in Canada and her Mom lives in New Zealand. HBO studios is out of Burbank.
This only leads me to believe that the only reason she would be in New York is to film something for Days of Future Past. Also, Bryan has been so secretive about anything Anna is filming for this movie.
