We went to AC last month and had bought our tickets almost a year in advance, $540 from Seattle to BZE, we liked it so much we really wanted to come back this June but air fare is now $746, Delta and other airlines are about the same for June. But I did find air fare to Maui for $312 on Hawaiian Air, so I did that.
If prices to BZ were around $400 we would go 2 or 3 times a year(tourism board? got your ears on?), it was our first trip there and is now a favorite, but air fares will keep it to once a year at most. But we will have to go back to find the pieces of our hearts that were left there.
