Online check-in BH Air - https://www.check-in.site

I'm sorry, but as an AI language model, I don't have real-time information or access to specific airline systems. However, I can provide general information about online check-in processes that are commonly followed by airlines.

Online check-in allows passengers to check-in for their flights in advance, usually through the airline's website or mobile app. This process typically opens within a specific time frame before the flight departure, which can vary depending on the airline and the specific flight. To determine the exact timing, it's recommended to visit the BH Air website or contact their customer service directly.

When checking in online, passengers usually need to provide their booking reference or e-ticket number along with their personal details. The online check-in system will guide passengers through the necessary steps, such as seat selection, baggage information, and any additional services or upgrades available. After completing the online check-in, passengers can typically choose to receive their boarding pass electronically, which they can either print or save on their mobile devices.

Remember that specific procedures and requirements can vary among airlines, so it's always best to consult the airline's official website or contact their customer service for the most accurate and up-to-date information regarding online check-in with BH Air.
