Very sad news indeed. I've been dreading this announcement for a long time, as the legacy SQ-DL pairing made little sense in an age of alliances. Being partnered with DL/NW, UA, US, and CO was just too much.
My flight next week on a Megatop might be among my last.
This partnership has been good to me for many years, and it's been a key value proposition for SkyMiles in my book. Since 2003, I've redeemed six SQ J and eight SQ F awards between the US and SE Asia, with one F still to fly this month and one J next April. Sure, the fuel surcharge passthrough has sucked, but still, 140,000 SkyMiles for SQ F has been a good deal.
KE is nearly as good as SQ, IMO. But the blackout dates and lack of F awards really bite. Here's hoping MH stays in the SkyMiles fold, availability at low award levels is good, and FIRST awards become available. (The last is a hope in vain, I know, but still....)
