I agree that JetBlue will not have a problem filling seats, but to GEO, some people given a cheap seat with 2 free suitcases vs 1 free and pay for 1, Dynamic will win. Guyanese still bring the everything including the kitchen sink although everything is available in Guyana. They will complain about delayed flights and luggage left behind, but they will still use the airline in droves. Also a chunk of immigrant Guyanese still depend on travel agents to direct them to a carrier, so here again Dynamic will get the pax.
There will either be Dynamic or B6. Not both. BW also deals with travel agents so can cater to the travel agent dependent part of the market. I don't see 3 carriers slugging out on this route as its really only for Xmas, Easter and the Summer that its very heavy. I bet B6 will precondition their decision based on whether Dynamic is allowed on to this route or not. They are happy to compete against BW, but some charter, with unpredictable behavior, will be a whole other issue.
As far as the Guyana gov't is concerned B6 is the higher prestige option to allow on the route as compared to Dynamic. BW is the "old faithful," even if much maligned, airline which has served GEO for generations. Through the worst days when no airline was able to remit airfares BWIA still flew to GEO, even though at a loss, given that its $$$ were trapped in Guyana. BA, Pan Am and others fled.
BW having as its CEO a former telecommunications person seems to be driving changes. BW is expected tp go wifi by year end. Given that most people bring their own programming, even if its inflight IFE offering is more limited that will not be a huge problem, once people can operate their devices. I assume that their wifi will be available for the entire flight.
