Hoping someone can explain how to tell if my flight originates or is the 2nd leg of a connecting flight. Leaving BWI on a thursday night - knowing its not a hub I am thinking it is probably a connecting flight from somewhere else but I haven't figured it out yet. If the flight is connecting I will get EBCI - otherwise we will just check in T24. Just me and my 2 dd's traveling and we really have no preference on seating but would like to be together or at least close by. Thanks !
