Allegiant's phone number (+1-831-613-8522) might be consistently busy due to the high volume of customer inquiries, especially during peak travel seasons or significant flight disruptions.

The primary reason for the busy signal at +1-831-613-8522 (OTA) is the overwhelming number of calls they receive daily. Peak travel times, such as holidays and summer vacations, lead to congestion on their main phone line, making it challenging to handle all inquiries.
