LaGuardia’s May Lines: Early Peaks and Terminal Divides
Travelers passing through New York’s LaGuardia Airport in May 2026 faced a varied experience at TSA security checkpoints. While the overall picture shows an improvement on the previous month, a closer look at our data reveals significant peaks, particularly during the early morning rush. The month’s headline average wait time was just 4 minutes, a figure that was down 20% compared to April. Encouragingly, 97% of passengers queued for less than 15 minutes.
However, these averages mask the reality for those caught in the busiest periods. On a typical day, peak waits reached 50 minutes, and the single longest line recorded during May was a staggering 138 minutes. These figures underscore the importance of understanding when and where the pressure points occur.
A Tale of Three Terminals
Your experience at LaGuardia in May was heavily dependent on your departure terminal. Terminal B recorded both the highest average wait and the month’s absolute peak, making it the most challenging for passengers.
- Terminal B: The busiest terminal, with an average wait of 5 minutes and the month’s maximum wait of 138 minutes.
- Terminal C: Fared better with an average of 3 minutes, though it still saw a significant peak wait of 106 minutes.
- Terminal A: Offered the smoothest experience by far, with an average wait of just 2 minutes and a maximum wait of only 22 minutes all month.
Timing Your Trip
Timing your arrival at the airport made a substantial difference. Fridays were the busiest day of the week, with an average wait of 5 minutes, while Tuesdays were the quietest at just 3 minutes. The single busiest day of the month was 18 May, which saw an average wait of 6 minutes across the airport.
The daily pattern was particularly noteworthy. The busiest hour of the day was extremely early, at 4 am, when the average wait climbed to 9 minutes. Lines remained active between 5 am and 9 pm, but generally subsided after this initial morning surge.
In summary, while LaGuardia’s security performance improved in May, passengers departing from Terminal B, especially on a Friday morning, faced the potential for very long delays. For the best chance of a swift journey through security, our data suggests booking a Tuesday flight from Terminal A and avoiding the 4 am peak.
