Duplicate Flight Plans from CYVR

I notice in “Scheduled Departures – CYVR” that virtually every US-bound departure has two filed flight planes departing at the same time. One plan has an “unknown” Estimated Arrival Time. The second shows a time estimate.

I see that ASA632 to KLAX (5:00 departure) has two “unknown” EATs.

This phenomenon is quite obvious when you sort the [More] Scheduled Departure list by destination and all ‘K’ destinations are grouped together.

Why is this happening?

Yup, some kind of bug here. Looks like when a plan is re-filed the original is not getting deleted. Example:

13-Mar-2006 A319/W Cancun Int’l [MMUN] Victoria Int’l [CYYJ] 11:11PM GMT 09:16PM PST Scheduled

13-Mar-2006 A319/Q Cancun Int’l [MMUN] Victoria Int’l [CYYJ] 10:46PM GMT 08:51PM PST Scheduled

13-Mar-2006 A319/W Cancun Int’l [MMUN] Victoria Int’l [CYYJ] 10:46PM GMT 08:51PM PST Scheduled

13-Mar-2006 A319/Q Cancun Int’l [MMUN] Victoria Int’l [CYYJ] 10:46PM GMT 08:48PM PST Scheduled
