YYZ-ORD-YYZ. Booked flights on American Eagle online then realised that they use rather small aircraft and regretted it! However our return flight from Toronto to Chicago was pretty good. Check in and bag drop was fast efficient and the AA staff on duty were courteous and friendly. Admiral's Club lounge was ok at both ends - complimentary glass of wine in ORD. Both flights on time and the advantage of these smaller Embraer 145s is that they can be filled and unloaded quickly. Efficient FA each way if not over friendly and complimentary soft drinks served. Seat belt sign on for duration of flights each way a few bumps here and there. Seats were comfortable enough for a one hour flight and leg room was ok (neither my partner or I are particularly small people). Landed early at Toronto and sat on runway for a few minutes waiting for gate to become available. But all in all a pretty good experience for the fare.
