JetBlue is considering revising parts of its operations after having the worst ontime record for US airlines in December.  The carrier blames much of the tardiness on the congestion at JFK, which it hopes to circumvent by turning aircraft around faster.  But they also are looking at adding 10-15 minutes to the arrival times of its 10 most delayed flights.  Is that cheating?  Is that really a solution?  Maybe it is, but doesn’t it sorta feel wrong?
