1. Chicago O’Hare International — Sun. between 8 am – 9 am (30 – 45 min)

2. Hartsfield-Jackson Atlanta International — Mon. between 7 am – 9 am (30 – 45 min)

3. Dallas/Fort Worth International — Sun. between 6 am – 7 am (15 – 30 min)

10. San Francisco International — Thurs. 8 am – 9 am and Fri (15 – 30 min)

This data was collected by the Transportation Security Agency (TSA) and analyzed by InsureMyTrip. Data only includes standard wait time estimates for the busiest US airports, based on the latest historical data available. Does not include wait times for TSA PreCheck passengers. Los Angeles International is listed as varied wait times, due to no clear day and time when extended wait times are more likely to happen.

Both the TSA and Customs and Border Protection (CBP) provide information on wait times at airports and border crossings.While security wait times are dynamic, travelers can check crowd-sourced airport security wait times by using the My TSA app prior to departure.

Best Protection for Flight Delays

Based on these data results, travelers can make smarter choices about their travel plans and travel insurance purchases. For example, passengers with departing flights at busier airports are more likely to utilize a travel delay benefit and, therefore, may want to compare travel insurance policies with better delay protection.

Travel delay benefits vary with each travel insurance provider. Typically, the wait period for travel delay benefits go into effect is between a 5 and 12-hour window. The benefit is designed to provide reimbursement for reasonable meals and accommodations while unable to travel.

Tip: Travelers must be delayed for a certain number of hours before this benefit can be applied. When comparing travel insurance, look for the minimum delay time (typically, starting at 5 hours) to start qualifying for coverage as soon as possible. 

Best Protection for Delayed Bags

Travelers may also want to ensure baggage delay coverage is included under a selected comprehensive travel insurance plan. Baggage delay coverage generally becomes active after belongings have been delayed for a specified period of time, typically 12 or 24 hours.

Tip: When comparing travel insurance, look for a maximum per-person coverage amount. For example, some policies may offer a more generous max limit, like $500 per person to purchase incidentals.

Best Protection for Missing Cruise Departure

For those concerned about a delayed flight adversely affecting a cruise or tour departure, travelers may also want to ensure a missed connection benefit is included under a selected comprehensive travel insurance plan.

This benefit is designed to provide travelers with coverage if a delayed flight (for example, of 3 hours or more) causes a traveler to miss a cruise departure.
