I agree with everyone that free 2 year lounge pass is very easy to achieve. I’m amazed that lounges aren’t busier. For my recent stays only NY Barclay and Bangkok were even approaching 50% occupied. I expect 40 nights to be dropped leaving 70 nights for the pass. Either that or only cash nights will be milestone rewards qualifying, (ie redemption nights won’t count). If the reward does move to 70 nights only, I would dump Accor and Hilton and become more loyal to IHG.
Personally, I’d be horrified if a limited number of lounge vouchers was offered instead. We have plenty of weekends away and very few long trips. We have seven future IC reservations in the forward diary and only one of these is for 7 nights.
