Planning ahead and packing properly can facilitate the screening process and ease your travel experience at the airport.

Even if an item is generally permitted, it may be subject to additional screening or not allowed through the checkpoint if it triggers an alarm during the screening process, appears to have been tampered with, or poses other security concerns. Read about civil penalties for prohibited items.

For items not listed here, our AskTSA team looks forward to answering your questions 365 days a year; live assistance is available from 8 am - 6 pm (ET).
