“ADA” (also known as the Americans with Disabilities Act) seating is a designated area or seats where individuals with disabilities can sit to help accommodate their needs much better than traditional seating. This type of seating is very common for the handicap and individuals in wheelchairs. When looking for this type of seating on TickPick, you can determine if a seat is ADA or wheelchair accessible by locating the wheelchair icon on the ticket listing or the disclosures marked in the seller notes stating the ticket as such.
Some venues will allow for individuals who may not require ADA or wheelchair accessible seating to occupy these seats. However, it is always best to double check with the venue first or simply look for tickets not disclosed as such unless you are actually with someone who needs this type of seating.
