Of course the problem with "Priority" Pass is that you'll often be turned away at lounges, because the card schemes only pay lounge operators a fraction of the amount they get from full-service airlines for premium/status pax - so they only let in Priority Pass holders to fill in the troughs between full-service airline departures. This is particularly prevalent with UK lounges and at airports dominated by budget airlines, such as STN/LTN/MAN, due to the number of people holding Priority Pass cards and the like.Lloyds World Mastercard for £15 a month is a way to get Priority Pass unlimited for far better than actually paying for Priority Pass itself
You can now pre-book entry at a number of airport lounges, but it slightly defeats the object if you have to pay an extra ~£6 every time (if you want to guarantee entry). Even then, pre-booking is often unavailable during peak periods (e.g. school holidays).
Realistically I think easyJet plus for £249/year has a lot of appeal if you live near to one of their main hubs (e.g. LGW). There's currently a 15% discount (available to MasterCard holders, i.e. basically everyone) if you sign up by tomorrow. It gives you guaranteed emergency exit/front row seat and extra cabin bag, plus priority security and boarding, which is most of what you get with status (except lounge access, of course).
