Avianca AV · a full-service airline from Colombia · Star Alliance

On our record, yes when it drops: the 5 Avianca fares we posted in the last year ran a median 59% under the guide price for routes of that length. The lowest was US$287 from Miami to Guayaquil. The guide price is a published-fare table scaled by distance, not an airline's own list price.

60% of the fares the server re-priced on their exact dates were still there, and the ones that expired lasted a median under an hour. Fares that vanish within hours are usually mistake fares; the rest are sales.

Most of its deals on our radar left from MIA (1), YYZ (1), BOS (1), BCN (1), to 5 destinations. Each departure airport has its own page with everything we found from it.

The sources named these fare classes: none named by the sources. A basic fare usually means no seat choice, no changes and a carry-on only; the deal page says which class the price is for when the source did.
