Jet Blue is about $500, but JFK is very far and the only non stop flight to Aruba leaves at 7 am, which is ridiculous. Delta is also cheaper. It is just United that is gouging, it appears. I have elite status with United which gives me perks like pre-boarding and free baggage check so between that the and flight times and proximity to Newark, I don't want to fly other airlines. When I called United, they told me the planes for the flights I wanted were empty, so supply and demand don't appear to be the reason. Maybe it is the expectation that there will be demand. I am just baffled. I hope this is not a trend.
