If you’re flying Avianca internationally from basically anywhere on their network, you’re pretty much guaranteed to be flying through Colombia en route to your final destination, which probably means a stop at Avianca’s hub in Bogota. It’s an awesome city and to encourage people to actually explore Colombia, rather than just flying through it, the flag carrier has implemented a free stopover service.
How to book a stopover…
To book a stopover, book your flight using the “multiple cities” option on Avianca.com and ensure there is a stop in Bogota when making the booking.
So long as there is a stop of no less than 8 hours and no more than 24 hours there should be no issue.
