A note for any Canadians on here - I've had a lot of success booking through cheaptickets.com in USD and using their 18% off codes, while letting my CC company handle the conversion to CAD. When comparing prices in CAD on kayak.com and such, you almost always come out on top booking in USD and using the 18% code. I recently booked a hotel in Chicago and saved $200...good hack for anyone looking to save a bit! On a different note, anyone know of any codes which run in to January 2017? Trying to book a place for NYE but most codes only apply until 31/12. Help would be very appreciated!
