I booked on United but it was really Air Canada. It was very confusing when I went to the airport. The ride to NY was very turbulent and shaky. The ride back was better. It would be nicer with more leg room and to get rid of the tilting the seat back thing. Fine for an hour flight but any longer would have been not great. Please put subtitles on the programs so we don;t have t use headphones if we forget them.

What is good to know if travelling to Ottawa?

  • The annual Canadian Tulip Festival is the largest of its kind in the world, and takes place every May through Ottawa and Gatineau. The festival dates back to 1945, when Queen Juliana of the Netherlands gave a gift of 100,000 tulip bulbs to Canada. Today, the festival showcases tulips throughout the city, with more than three million tulips on display for ten days in May.
  • Canada Day, on 1 July, is celebrated best in the country’s capital. Major events take place throughout the city, but the focus of the entertainment is (understandably) on Parliament Hill. Hundreds of thousands of people take to the streets to celebrate with concerts, street displays and fireworks in the evening.
  • Parliament Hill is the first spot most tourists visit. Don’t miss the sound and light show which runs on summer evenings. Half an hour long, the film about Canada is projected onto the Parliament Buildings accompanied by fantastic lighting effects. The show is free and no booking or tickets are required.
  • The Byward Market, east of downtown, is a huge neighbourhood, characterised by its open air market stalls. Fresh fruit, vegetables, flowers and art are all on sale in the stalls, while the surrounding shops have become increasingly boutique in recent years. Visit during the day for some shopping or browsing, or at night time for some of Ottawa’s best restaurants, bars and clubs.
  • For open air pursuits, the Rideau Canal is one of the best spots in town. Boat trips are available, for views of the city by water. These can usually be arranged at your hotel or at the canal. The banks of the river are popular routes for joggers and cyclists. Best of all, when the canal freezes over in the winter, it is transformed into a huge outdoor skating rink.
  • When is the best time to fly to Ottawa?
