Vivacolombia is a low cost carrier. They are really strict on dimensions of baggage and weight. Be sure to read the fine print or you may need to pay excess baggage fees at the last minute.
The Medellin-Bogota flight is a short hop, only 45 minutes. With Avianca you'll be offered a small cup of Coke or a juice box. Vivacolombia will sell you a snack if you want it.
The advantage of Avianca is they have so many departures daily on that route. Vivacolombia is normally on time, but when a flight is delayed you may be waiting around for three hours while they adjust their schedule. On Avianca they would just shift you seamlessly onto an identical flight leaving half an hour before or after.
