A weather delay does not need to be caused by weather at your departure or arrival airport. If their is weather enroute, the aircraft must be diverted around it. This deviation from the originally planned path of flight adds time to said flight. So if your aircraft flew ORD
and had to fly around weather, it now arrived at Boston late due to the added length of the flight plan, and having to fly around it again on the way back to ORD
delays the arrival the next flight.
Also, if their is bad weather at *any* point in the day at ORD
, every single flight after that has a 99% probability of being delayed. That airport handles so much traffic that once it backs up, even slightly, it stays backed up for the rest of the day. It has to play catch-up, and that means delays. Especially if a particular aircraft is doing multiple turns in and out of ORD
over the course of the day.
1.2 hours to make a connection in ORD
is not unrealistic. Many, many people makes those connections. Unfortunately, you haven't had the best luck these past coupleof weeks! It happens.
If their was weather enroute from BOS
, the ERJ-135 would have to be weight restricted. Also, it depends on the headwinds. Every aircraft is affected by headwinds. That could have been a factor.
Sorry to hear about your dilemma this time! I'm sure things will work out sooner or later. Hope this helps a little bit!
Prepare doors for departure and cross-check.
