I fly B6 to ORD often and have been impacted by IRROPs several times this year primarily due to weather. I can tell you from firsthand experience that the crewmembers at ORD are some of the nicest ones in the entire JetBlue system and I've been to a lot of Blue cities and am about to add 2 new ones in the next month. They will help you get where you need to go as quickly and as safely as possible. I've been stranded for a few hours and have been stranded overnight. No airline can control the weather. I would hands down choose them over Delta regional especially on a business route like BOS-ORD. On Delta, you'll be stuck amongst business travelers with status whereas on JetBlue everyone has an equal experience.

My only beef with JetBlue is earlier this year I was impacted by them cancelling flights 2 nights in a row due to bad weather in NY and then Chicago. I was lucky and went standby on a morning flight just for the heck of it and was the only standby who got on the flight. There were at least 20-30 people on the list including a lot of pilots. Had they pulled an Air Canada and just sent an A320, the entire standby list could have been cleared on one flight. The plane was coming from NY so I don't want to hear that an A320 wasn't available--I've had them subbed for E190s many times. This is the type of forward thinking that just isn't the norm at JetBlue. They knew the flight the night before was cancelled and that the next night had the possibility of being cancelled. The ones in between were full. And they know what the standby list looks like in advance. Instead, it probably took a good 3-4 days to recover when it could have been done in one flight.
