This takes me back to our trip last year on Openskies....
see trip report
I would definitely fly Openskies again, the lounge isn't much to write home about at ORY but the whole experience in Biz Bed was just a cozy time with great staff. The BMW was a right result! Im planning on going back to LAS next year via SFO/LAX. For us the Mandarin Oriental is just a great haven in busy Vegas.
Edit. Just convinced Mrs C for us to fly EC again if another IB deal comes up we had such good memories.
How much did you pay by the way?
