Hi Everyone,

I am new and recently join this interesting miles collecting adventure.

Previous I had a thread on United vs Delta. Thanks everyone for replying to that thread.

Now, I am just wondering, among so many airline programs, which is the best one? I am thinking of focusing all my future travel on one airline, thereby maximizing my chances of racking up more miles in the shortest period of time.

Here are the ones I tried:
Delta: collected 35000 points
United: 2500 points
Korean Air: 13,000 points, this one is my favorite because of the A380.
Cathay: 11,000 points
Japan Airline: I will never sit this airline again, horrible customer service.
Air China: I will never sit this airline again too, horrible food.

Here is my situation:
1. I live in NYC. I don't mind using any of the airports here.
2. I fly frequently within the country (USA). I love to buy the cheapest ticket to save cost yet at the same time would love a complimentary upgrade. Using points to buy tickets isn't really my goal, rather I hope to achieve a million miles and get lifetime Elite status, so I can get upgraded easily with a cheaper ticket.
3. I fly to Singapore a few times per year. 2-3 times.

Which airline program do you think will best suit my situation? Are there any other airlines' program I should try?

In addition, what do you think is the best and fastest way to rack up miles?
