There is a dedicated forum for hand analysis, and in this thread you can read a guidance to the best way to share a hand:
CardsChat makes it easy to share your tournament poker hands for analysis by other poker players. We break it down for you step-by-step.

888 Poker have downloadable hand histories, so next time try to find that and use the hand converter, so that we get all relevant information. As 300HPGOD say, the stack sizes of players not involved in the hand is important on the final table. If someone is sitting with like 10% of our stack, we dont want to bust before that player and allow them to fold their way to a payjump. And this will affect our willingness to get it in against other larger stacks. Not so much here though, since you have BTN covered. And even though you happened to run into AA here, AKs is a really good hand. So in game I would not have spend much time to think about it, and I would also have overjammed.
As 300HPGOD say, we can use software to find out, what range we give action with in a preflop all-in situation. To get the exact answer I would need to know all stack sizes and the payouts. However the payouts are fairly similar on the final table for most MTTs, so I just picked a random 888 MTT for the payout structure. As for stack sizes I gave LJ (the original raiser) 70.000 chips, HJ 20.000, CO 90.000 and BB 60.000. This leans a little towards a worst case scenario, because LJ can bust you, if he overcall, and HJ, who already folded, is fairly short. I then clicked "calculate", and the program now determined the NASH ranges, which are the game theory optimal ranges, where nobody are winning or losing:
LJ min-raising range: 18% of hands
BTN jamming range: 8,2% of hands
Hero overjamming range: 2,7% of hands - JJ+, AKs
LJ overcalling range: 0,9% of hands: KK+
So this is actually a bit closer, than I thought, and AKo would be a fold. The reason for that is, LJ is supposed to open fairly snug, and BTN is then supposed to adjust to that by rejamming fairly snug. Its one of those rare situations, where I think, real world ranges might actually be a bit wider on average. And as I said, its also sort of worst case, since I gave HJ a short stack of only 20.000 chips, which puts a lot of ICM-pressure on everyone else. So lets change the CO stack to 60.000 chips and run the sim again:
LJ min-raising range: 18% of hands
BTN jamming range: 11% of hands
Hero overjamming range: 3,4% of hands - TT+, AK
LJ overcalling range: 0,9% of hand: KK+
As we can see the LJ ranges dont change, but both BTN and Hero should now be a bit more risk willing, because they dont have the same incentive to fold and try to outlast CO. Heros range now also include TT and AKo, which mean, that AKs is now a very clear overjam, whereas it was a bit marginal before. So the conclusion is, that unless there was someone with an even shorter stack than 20.000 chips, or multible players with such short stacks, then this was a fine jam, which just did not work out this time.
