I agree the linked article is crap, but buried deep within is a valid complaint about B6's lack of interlining policy which makes irops rebooking fraught with peril. I was at BOS one sunny Monday afternoon a couple of summers ago when our flight to IAD was cancelled, a lot of connections got blown up... and you should have seen the faces of business travelers heading to IAH, DEN, etc. when they were told they'd now be arriving at the destination late Tuesday night.

There are about 75 other ways to get from Boston to Houston on a Monday afternoon but B6 wasn't going to rebook distressed pax on any of them. Those customers had the choice of taking a 24-hour delay (which made it a trip in vain for most, obviously), walking over to UA or DL and buying a very costly walk-up ticket, or giving up and going home.

B6 could fix that and retain more customers with an interlining agreement, but they don't. So "waiting until the next day" can indeed mean poor customer service, and it's the main reason JetBlue is no good IMO for business travel. Starting my trips at a distant B6 outstation (SEA), if a flight goes tech, it's no good for me to hear I should just come back to the airport in 24 or 48 hours because that's when the next open seat on JetBlue is available.
