Keflavík used to be a terrific airport, but Iceland’s Instagram fans have meant it is completely inadequate for the number of people passing through.
I’d also add Vancouver to the list of wonderful airports - you can spend ages looking at the amazing First Nations art to fill out the long waits.
In any list of terrible airports, the shopping mall that is Heathrow deserves a special mention. It manages to be huge, cramped, soulless, depressing and bewildering at the same time - all drenched in the stench of duty-free perfume.
