In April this year, Which? surveyed almost 5,000 members about their experiences at airports in the previous 12 months.
Respondents were invited to rate the airports across 11 categories, including seating, staff, toilets and queues at check in, bag drop, passport control and security.
These experiences were then combined to give each airport an overall customer satisfaction score, from 0-100 per cent.
