We examined 30 of the busiest international airports worldwide based on the Port Authority of New York and New Jersey’s 2022 Annual Airport Traffic Report. Then, we ranked them based on their scores out of 100.

Scoring Process:

• Each airport was assessed on multiple factors, with a normalized score out of 100 assigned for each criterion.
• Individual scores are combined, considering weights based on importance.
• Applied appropriate weights to normalized scores to create a composite score for each state.
• The final composite score ranged from 40 to 80 for a realistic assessment of airport performance.

Data Handling:

• Only actual values were stored in the final dataset. Individual feature scores were removed.

Criteria Analyzed:

• The total number of passengers passing through the airports.
• According to the Official Aviation Guide of the Airways (OAG), we derived Average On-Time Performance:
• Focusing on the cost of a week’s parking using the cheapest available option (e.g., long-stay car park, economy parking), we derived parking fees.
• Considered the cost of the shortest available parking slot for dropping off passengers outside the terminal building.
• The number of restaurants and bars within the terminal buildings.
• The number of duty-free shops within the terminal buildings.
