Some consumers are voicing concerns about online flight and travel prices.

Karen Cherepak says she planned to book a spring break getaway to Mazatlan and though she'd found a great deal online.

When she clicked "book now" the final price was more than expected.

"As soon as I clicked on the $659 price, it jumped to a $1,100, says Cherepak.

She tried again on another site and found a WestJet vacation on the website for $539 dollars plus $124 in taxes, but when she clicked to book, the price jumped to $1,419 per person, plus $130 in taxes.

"I would like to see proper pricing," says Cherepak.

CTV News went to the website and found a similar thing, with a price that rose by $192 after clicking to book it.

The Consumers' Association of Canada says it receives regular complaints about flight pricing online.

"It's a very solid complaint. I don't know the numbers, but we get hundreds every year. I haven't heard of one being resolved," says Bruce Cran of the association.

WestJet says it's been experiencing problems on its website and so the prices are not as up to date, so it's advising customers to go through a travel agent or its call centre for more accurate pricing. says it allows airlines and tour companies to update pricing every three hours on its website but it relies on those operators to update availability and pricing at that time. If they don't, the most accurate pricing and packages aren't available to the public. advises its users to look early and often, avoid peak times, and suggests prices will then be more consistent. Prices may also be lower if consumers are flexible with their travel dates.
