Making a connecting flight with only 8 minutes to spare is no easy feat!
It takes a lot of planning and quick thinking.
In order for you and your luggage to make the flight, it’s likely that the airline staff had already pre-arranged for your bags to be transferred onto the next plane before you even arrived at your gate.
This means that they were able to quickly load them onto the new aircraft without having to wait on you or any other passengers.
Additionally, if there was time remaining after loading all of your luggage, they may have also helped speed up boarding by allowing those with tight connections like yourself priority access so that everyone could get settled in their seats as soon as possible.
