Pot odds with two cards to come

Suppose you hold Ah Kh and the flop comes

2h 4h 6s

You're pretty sure your opponent holds AA.
Let's pretend the only way you can win is by hitting your flush.
The pot is $10. Your opponent bets $5.
It comes around to you. The pot is $15, and it takes $5 to call, giving you pot odds of 3:1. Let's ignore implied odds (your opponent knows you're on a flush draw and will fold if you make it). Also assume nobody is all-in.
Here's where the confusion is. Many poker sites recommend using the odds of hitting the flush on both the turn and the river to calculate pot odds. I myself used to calculate pot odds this way as well. You're a 2:1 dog to make the flush draw with two cards to come, making the call profitable.
However, it recently occurred to me that this method assumes that your opponent doesn't bet on the turn, or else you would have to pay extra to see the river. So does the proper way to calculate pot odds on the flop only take into consideration the next card to come (the turn)? Continuing the example, this means you're a 4:1 dog to make the flush on the turn, making the call unprofitable.
Does this means that you should fold a flush draw most of the time on the flop, unless it's a multi-way pot?

Well if you think your opponent has AA(kinda silly narrowing his range to just aces somehow) why would you call with AK pre? And if you know he knows your on a flush draw and is gonna fold if you make it then why would you call with improper pot odds?

The only time to use the 4x rule is if your are going to see both cards(all the money is going in on flop). Otherwise use the 2x rule.

Maybe it's just me, but I'd take my stack into consideration, too. And how are we so sure they have a pair of Aces? I'm assuming this is a micro or low limit game and so a bet of $5 is consider huge and leads you to believe they have a great pocket hand. Otherwise, if this is a $1/$2, a call of $5 wouldn't necessarily be shouting "monster hand" to me, probably a good hand, but not a monster.

If I have a good chip advantage on him/her, I'd probably bet into it and perhaps even raise enough to put the pressure on. He/she knows you have a good chance of hitting that flush, so now if you raise they have to ask their self if they feel confident you won't hit the flush. Not only that, but with the flop you have, they also have to question a straight. Then again, how can you know for sure they don't have the straight in lieu of the aces you feel so confident about.

If you call, you still have good odds of getting the flush, and if you have the chips to spend without putting yourself in a problem situation, I think it's money well spent. The turn card is going to determine a lot here. Let's say it turns king. Sure you're pair of kings doesn't hold a candle to the aces, but you've now gained an extra out. A third king gives you trips and you still have the possibility of a flush on the river. If it turns an ace, I'd get out of it and move on to the next hand - but that's only assuming that you actually know what they hold the other two aces - because in reality, you wouldn't actually know that.

If you don't have a good chip advantage, I'd probably just fold out and wait until a better opportunity came. It sucks knowing you won't know the outcome of if you would have hit the flush, but it sucks worse when you don't hit it.

Taking into account the OP, I would fold. 2 to 1 pot odds, with no implied odds of getting paid if you hit? not worth it.

I like to be getting at least 4 to 1, but I prefer 5 to 1 odds on flopped FDs.

People in general waaaaaaaaay overplay FDs IMVHO.

Oh yeah I forgot.

If you are calculating odds for seeing both turn and river, you need to call a turn bet too. I usually calculate for just one card to come, and re-assess on the turn.

If you jam the flop (or call a jam), and are gtd. to see turn and river, then you can calculate that way.

No because
1) In reality opponent doesn't always have AA.
2) You should take implied odds into account, they wont always fold to possible flushes on the board.
3) You have good pot equity so raising as a semi-bluff is often better than calling. Playing draws aggressively ftw
