Which lounge in which airport with what airmiles? (Depending on that, the answer might be yes, no or maybe!)
Be aware that you can't currently buy access to the BA lounges with Avios (and I haven't heard any rumours of that starting any time soon either). All you can do is buy access to third party lounges Raffles wrote up the options last year, and it's a good post on the topic: http://www.headforpoints.com/2016/08/09/use-your-avios-points-for-airport-lounge-access-2/ Conclusion was that it wasn't normally very good value, and you'd be better off doing a discounted cash booking through one of the methods detailed in the article
My favorite option is the app loungebuddy. They often offer free entry to their new lounges (instructions given via newsletter) if you happen to travel at the right time to the right place.
Avios are generally very valuable when redeemed for flights. Why do you want to use them for Lounge Access?
Agreed with this. I think it's generally regarded that you get poor value for your Avios when using them to buy lounge access. This article has some good tips on how to get into lounges without having to use Avios (so you can save them for more valuable redemptions like flights/upgrades): http://www.moneysavingexpert.com/credit-cards/cheap-airport-lounge-access For instance, if you're a Flying Club member, you can get into No. 1 lounges for £25 (and earn 350 miles!). https://no1lounges.com/virginatlanticflyingclub
Was on a BA flight this morning and found the attached offer in the inflight magazine for Priority Pass. Not heard of it myself but had a quick gander and membership gives you access to 1000+ lounges worldwide. Might work for you. 1 year standard membership is £62 with the 10% off code in the advert. https://www.prioritypass.com/en http://imgur.com/a/ISjOy
Does that include any visits? If not, that's not a great deal as you'd have to then pay for every visit, often £15/person/visit The other downside with Priority Pass is that you're bottom of the heap for access, so any busy lounge (eg Aspire in LHR T5, most LGW lounges) won't let you in If you'd be making heavy use of Priority Pass, it's normally best to get the UK Amex Plat chargecard - £450/year, but gets you 2 Priority Passes with unlimited visits, each of which is valid for cardholder + one guest
Yes, you're right. The standard £62 membership doesn't include any free visits (£15 each). It goes up to £142 for 10 free visits (£15 per visit thereafter). The unlimited visit card is £233 so the Amex Plat chargecard that you mention is a decent deal if you think you'll use it often.
For many of the UK lounges, you can normally buy access in advance for about the 20 quid mark, plus that means you'd get entry even when the lounge is busy, so do you sums first!
Personally I wouldn't use miles on lounge access. For me, the miles are more about getting cheap flights
