This might be a very geeky question, but the flight number set 952/953 would by United's logic be a transatlantic flight originating from ORD and possibly continuing on westward within the US. However, starting next year this number will be used on a transatlatic from IAD. This got me a little confused. Does anybody know whether the numbering system has changed?
