Summary

If you buy day passes at airline lounges (typically $50 in the US, but not widely available in the rest of the world), and you use the lounge network of Priority Pass, then this can be a good saving as the per-entry fees are pretty reasonable. I am tempted with the Standard Plus offer – £12.70 per visit is good value, for example when I am in San Juan, Puerto Rico in the autumn and will not have access to the AA lounge there as I am flying United.
