Noticed on a booking coming up in october that a flight was changed due to current timetables in place for october. Shows that the last flight to GRR (Grand Rapids, MI) from ORD is now 6:30pm. This seems ridiculous considering the amount of travelers that would connect to GRR in ORD after 6:30p. Currently, UA operates at least 2-3 flights from ORD to GRR at 6p or later. For the UA experts out there, should I expect a more accurate time table or is that it for the 4th quarter. I though airlines usually update timetables quarterly.
