I stupidly put most of my Amex points in Avios so now I can't redeem them for anything actually useful. I currently have 40k in Amex and 40k between Iberia and BA. I'm going to LIM or EZE for 2-3 months over winter and the next big trip probably won't be until NYE 2020. The issue is there's no good value way to redeem for these flights if I want to and I can't get it back out of Avios to spend on something better value like Amazon. Looking at flights I can get a return on Norwegian for £500-£600. Whereas it's obviously no go out of UK using Avios. I prefer to go to Argentina cos of the low peso but one advantage of doing Peru is that I'd have to connect anyway so I can try to redeem on ex-MAD flights. But that's still really bad value. e.g. MAD-LIM is £89 plus 35k points and 62k points for business. That 30k points would be worth £150 at Amazon and there's no way the perks of Business class over Economy are close to being worth £150 even on a 12h flight. I've looked at wine and car rental too and the £/Avios is atrocious, much worse than the already shitty Amazon rate. How else can I use these Avios?
