Given how few recovery flights JetBlue operated to return their passengers from SXM to the US compared to other airlines, and given their apparent invocation of Force Majeure in order to keep from giving refunds for cancelled flights, you need to decide two things. One is whether or not you have respect for them as an airline with which you want to do business. The other is whether or not you can live with their recent practices and policies. Perhaps the two are one and the same.
