I used to be a AC prestige member and currently have 140,000 miles with them. Last week I made a reservation online for my grandmother to fly from YYZ to LGA for the day for her grandsons graduation from medical school. I couldn't get through to confirm the flight and now the reservation has cancelled out and there are no more award seats left for the flights I need. The only thing available is a departure from YYZ at 9am and a return at 2pm same day. But, the graduation begins at 3pm.

I was told a couple of weeks ago by an AC rep that standby would be an option or that I could call AC the day before the flight and ask them to release a seat. However, today I was accidentally transferred to the Super Elite desk and the rep I spoke with stated that they won't release a seat or allow my grandmother to go standby. Purchasing a ticket is about $890.00 USD and flying Jetblue out of Buffalo isn't an option as my grandmother is in her seventies. AC is so difficult to get through to that I have decided to give my business to American. What options do I have to get my grandmother to NY for the graduation. Both LGA and EWR have no aeroplan seats.
