Frequent flier miles are a depreciating currency. Don’t hang onto them and never trust that they will maintain their value. The latest program to devalue is Avianca LifeMiles. You have until midnight (Colombia time) tomorrow to book under the old rates. Pay attention to the time zone so you don’t miss out!
The new award chart hasn’t been published (and won’t be until the devaluation has already happened) so it’s impossible to know precisely how much the program will be devalued. Accordingly, if you have Avianca LifeMiles, my recommendation is to redeem them now.
One of the most frustrating things about the LifeMiles program is that you can really only book what is offered online, and there are a lot of restrictions. It’s really best to use the program for simple point-to-point itineraries. You can book either one way or roundtrip itineraries. Unfortunately, the LifeMiles search engine is spectacularly stupid. A lot of itineraries fail to show up, even though they are available.
To search for flights, I recommend using the United search engine, which seems to work a lot better, to find an itinerary. Ideally, look for an itinerary involving only one airline. Once you find a workable itinerary on the United page (bearing in mind that only “United Saver” or “Partner” award space will be available when booking with LifeMiles), you can search for the same dates with LifeMiles. The LifeMiles search engine allows you to skip their “SmartSearch” option (which, in my opinion, is the opposite of smart) and select an individual airline. I have tested a few different itineraries and by using this method, have been able to make successful bookings that do not show up either with the “SmartSearch” or “StarAlliance” option.
Good luck, and burn LifeMiles now while you still can. At least Avianca gave advance notice of the devaluation this time. This doesn’t always happen.
