Thanks for the very kind words SQueeze. I'm no analyst, just someone trying to stretch his spending money like everyone else!

I hope you didn't take the commentary the wrong way. Of course, if you cannot tolerate long flights in more cramped economy seating and need a day or two of rest when you arrive just to recover, you are obviously not getting any value for money. These are all just rules of thumb to help you decide.

How has the Citi Rewards been working? That's 10x rewards when buying from a store that sells clothes, shoes or bags, and at 1,250 points = 500 miles, that's S$1 = 4 miles. Are there a lot of restrictions on what stores qualify, including for Internet transactions?
