I've been through the Ottawa airport and it looks really nice especially with the waterfall.
The only airport that I have liked is Fort Lauderdale in Florida but I haven't gone through too many airports in my life.
It appears the higher the cost of airpot fees the worse the customer service. Miami I hear is expensive to go trough and it also has the highest percentage of lost luggage.
BTW if you ever loose your luggage just ask them to look on the tarmac and also make sure they know where you're going. The last time my luggage was lost it went from Florida to Jamaica to US Somewheres to Quebec and eventually back to Halifax.
