... in response to Need help with Avianca, posted by zack on Nov 7, 2005I try and always fly Avianca/SAM and generally have  no problems.  Your problem with getting through is the heavy demand during the holiday season.  I would bet you will be had pressed to find anything between Dec. 12/Jan6.  Keep trying you will get through using 284-2622.  It's their reservation center in Medellin.
Push comes to shove try a travel agent.
BTW, service has really improved since Avianca was sold to a Brazilian company. The wife and I have flown several time Bogota/Cali; Bogotá/Santa Marta and Bogotá/Medellin and the change is amazing. Doesn't make any difference but the "new name" is Aerovias del Continente Americano S.A. Avianca but Avianca will do.
