Simple AJ question (Party 10+1)

AJ is one of those hands that befuddles me. This just came up in a Party 10+1 MTT. Is it weak-tight to fold given the pot odds, or should I assume someone has a dominating ace and just give up the ghost? Would it make a difference if it was AJs? Similarly, do you call or fold AQo here?

No way in hell am I flat-calling this. With your stack, I would give some consideration to a substantial raise, but I think I'm a lot more likely to lay it down. If it was suited, or AQ (suited or not) I might call, but I'm really not a big fan of calling in tournaments.
