As the summer travel season begins, most travelers rush to make connecting flights and many of those travelers rely on their e-ticket on their mobile device to board the plane. Free Wi-Fi is great, but speed is important too.

An airport’s wi-fi speed is vital to making your vacation start out on the right flight and to connect with people via phone or email at a departing or arriving destination.

Ookla used its network speed analysis tool, Speedtest,  to test the upload and download speeds at the most heavily traveled airports in the U.S. and Canada. It then produced a ranking of airports with the speediest connections.

These, according to Ookla, are the top U.S. and Canadian airports, in ascending order:
