The reason why the prices are so different is that price comparison search engines are either not searching live prices (which change by the minute), or that they are unable to calculate the price due to the airline complicating their pricing structure (these days, a price comparison engine has to ask you how many bags have you got, how heavy are the bags, how are you paying, can you print your boarding pass or do you have to check in at the airport, etc...).
Just go to the airline's site directly. You can find a complete list of who flies where on WhichBudget.com |
