The regional to mainline connection on your flight home might need a bit more time, esp if you gate-check carry-on baggage. If your RJ flight arrives at gate B84, all passengers must wait onboard the aircraft until groundcrew completes unloading carry-on baggage. If your RJ flight arrives at a jetbridge, only those passengers with gate-checked baggage need wait while others proceed directly in to the terminal.

Since one cannot determine gate assignments at time of booking (unless of course you book just prior to the flight's departure), you will need to allot extra time for regional to mainline connections.
