Four countries, seven airports and eight flights in three weeks was… not bad. In fact, it was pretty good. Making full use of lounges definitely takes the edge off the weariness of flying and sweetens the entire traveling experience.
For the most part, all the lounges that I visited on this trip (eight—we sometimes helped ourselves to multiple lounges in one airport) had similar amenities: free wifi, free food/drinks, lounge area, newspapers/magazines and showers. However, one stands out as being particularly great, and another stands out as substantially less than great. We visited both on the same day so the differences between these two lounges were made even more stark.
