On the Sky to Panama Canal departing 5 March and just got upgrade email Oceanview to Balcony... 27 days out. Ship was sold out in all categories except Inside last time I looked a couple of weeks ago. I did bid the maximum ($480 Canadian each) but it was still MUCH cheaper than booking a balcony at time of booking. Also using NCL Air - got decent flights and again MUCH cheaper than booking same flights direct (these were definitely best flights available from Ottawa to Miami and have bids in for Air Canada upgrades as well... )
