the first one shouldn't be too hard now

3- MDW INCORRECT for this leg LGA INCORRECT ML INCORRECT for this leg D9S INCORRECT for this leg (recall the clarification that the third departure airport is west of the arrival airport from the prior leg)
4- EWR INCORRECT IAD INCORRECT PE INCORRECT 737 INCORRECT for this leg
5- DCA INCORRECT FLL INCORRECT EA INCORRECT for this leg 72S INCORRECT for this leg (recall the fine fine print: there are two possible airlines for Leg 5, each operating a different type of turboprop aircraft)
6- MIA INCORRECT LHR INCORRECT BA INCORRECT 747 INCORRECT for this leg

decoding the red type:

• "Incorrect" with respect to an airport (e.g., LAX) can mean either: (a) it's not in the itinerary at all, or (b) it's at the opposite end of a different leg of the itinerary
• "Incorrect for this leg" with respect to an airport (e.g., ORD) means it's at the same end of a different leg of the itinerary
