Its a long-ish flight. Not sure how many in your party. It appears to be operated on ML, so you get the big chair. 150% AQMs versus 50% on Tango (I'm sure FLEX will be close to $400 more per person, but you'd need to call to confirm) That means Tango = 2165 AQMs, versus 6,495. You appear to de edging close to E50k, so *G is a nice perk...

Assuming its a trip for 2, and flying BID-ness goes a long way to impressing the ladies (or gents...) I'd do it.
