We just bought two tickets ZRH-LHR-JFK for 880 CHF WT+ compared to 690 WT. 100 more each way for WT+ is a no brainer for us. Especially when travelling in the 747 - I wouldn't mind that much if I could be upper deck in the A380. Also ZRH-SYD is CHF 2200 in PE with CX compared to 1500 (?) in E - also no brainer for me.
Flying is so cheap, even if you pay for J - I mean, try to walk the distance.....
