Yes, many airlines allow passengers with anxiety to participate in "Pre-Boarding," but you must take specific steps to request it. Under the Americans with Disabilities Act (ADA) and the Air Carrier Access Act (ACAA), anxiety is recognized as a condition that may require a "reasonable accommodation." Pre-boarding allows you to enter the quiet aircraft before the main crowd, giving you time to settle into your seat, stow your luggage, and mentally prepare for the flight without the stress of being bumped or rushed in the narrow aisle. To utilize this, you should approach the gate agent before boarding begins and simply state that you have a "disability or medical condition that requires you to board early for extra time or assistance." You are not legally required to disclose your specific diagnosis (anxiety) or provide a doctor's note, though having a "Hidden Disabilities Sunflower" lanyard can help signal your needs to staff. Most gate agents are trained to grant these requests discreetly. Keep in mind that while you board first, you will be on the plane longer as the rest of the passengers board, so bring noise-canceling headphones or a "comfort item" to manage any claustrophobia during the wait.
