Travel advisers say there's a lot to take into account when booking connecting flights, but a general rule of thumb is 60-90 minutes between domestic flights and at least two to three hours for international itineraries.
Is 45 minutes enough to catch a flight?
It is recommended to have at least an hour or more for connecting flights to allow time for any unexpected circumstances. However, if both flights are operated by the same airline and in the same terminal, 45 minutes may be sufficient.
Is a 40 minute layover OK?
The recommended layover time for international flights is generally longer, as you will have to go through customs and immigration before boarding your next flight. In most cases, a 30-minute layover for domestic flights and an hour for international flights is considered a minimum, or short, layover.
