A California-to-Honolulu flight was scrapped after heavy smoke filled the cabin on the runway, capping a rough travel day for Hawaii-bound passengers.

• Passengers had to get off the plane fast at San Diego International; nobody was hurt.
• Officials blame overheated brakes for the smoke.
• The mess was part of a wider bad day at the airport, with more than 200 flights delayed.
• One Hawaii resident heading home from the East Coast had already sat through an hour-and-a-half delay when a door would not shut properly.

Outlook: Travelers flying between the mainland and Hawaii should expect more delays as holiday-weekend crowds strain airports.
