I’ve been a strong critic of Delta SkyMiles. Theirs are one of my least-preferred currencies. I’d much rather have miles with United, American, or Alaska. I’d much rather have miles with Aeroplan, Singapore, or Japan Airlines. I’d much rather have miles with Korean Air in Skyteam.
Yet right now availability for summer business class travel to Europe is quite good at least on some routes. So redeem those Delta SkyMiles now for 62,500 miles each way.
