Yes, the strike is ongoing. No end in sight. There are articles in Spanish if you google it, nothing in English. I cancelled my trip for a full refund, however, 4 days later, flights still appearing. Might have to take it up with my CC at this point. As per Avianca customer service, it leaves something to be desired.
It also seems to me that the TACA subsidiary of Avianca is doing most of the flying, which was confirmed by an article in Spanish about the strike. The Colombian pilots are the ones whom are causing all the problems.
