Calgary Airport US Immigration PreClearance

[davidI]

Does anyone know what time the US Customs / Immigration office opens at the Calgary airport?

I have a 06:30 flight to Denver and don't want to arrive there at 4am if the Pre-Clearance Office does not open until 5:30 or something.

That's the only information I can find on them...possibly worth a call?

You can not enter more then 2 hours prior to your flight departure.

6:30am is the earliest US flight. Customs is open at 4:30am-8pm daily.

edit - also refer to roopi's post.

edit2 - Looks like there are 6am flights now. Custom hours still the same. Here's the link: http://www.yyc.com/News/tabid/91/articleType/ArticleView/articleId/149/Business-as-Usual-at-YYC-US-Customs-Border-Protection-Open.aspx

Thanks. Guess we'll aim for 4:30am then. Given my travel history and work visas from Yemen I always have issues entering the US. Sucks there is not MLL on the US side.
