A nationwide FAA ground stop caused a chaotic day of delays and cancellations for travelers at Honolulu's airport, though it's been lifted and the worst effects are already fading.

• The FAA ordered a nationwide ground stop, stranding passengers and canceling flights, with the impact in Hawaii felt almost immediately.
• Some travelers were bumped to other airlines after missing rebooked flights, while others got stuck between terminals for hours after being locked out of secure areas.
• Airlines warn delays and cancellations will likely continue into the weekend as crews and planes get back into position.
• Aviation experts say the system will take days to fully untangle, but they still consider flying safe since pilots follow strict procedures regardless of FAA communication issues.

Outlook: Expect lingering delays and cancellations through the weekend as airlines work to reset schedules and aircraft positioning.
