hello beela.. just an advice : if you are travelling to doha from calgary make sure to bring the required weight allowance only (it's 50 lbs/per bag) and as u said u r allowed to bring 2 suitcases.. ur friend is right that it is more wise to pay for an extra luggage than to pay for the extra weight coz it's more expensive.. and to doha it is way more expensive than fiji extra weight can cost u $400 and extra bag will cost u $250.. as far as i know US and Canada outbound flights have the same rule.. i always have this problem when i'm travelling from washington (IAD) to doha.. best thing to do - leave all ur heavy stuff and just shop in doha.. they have good shops there.. happy trip..
