The price isnt bad but you can do better. Do you actually want to go to Singapore or are you just looking for decent flight deals? If you just want the miles there are a lot of decent fares to HKG these days and that would be right at 18,000 EQM's. Also, since you are flying out of ORD then you might want to keep an eye on some premium economy fares on BA to Europe as it may be a bit less flying but get 50% bonus on EQM's for a premium economy fare and bit better seat.
If you are strictly domestic flier then I would be hard pressed to strive to hard for EXP but the SWU's and F lounge access on Intl flights would be worth it to me.
