London Travelers' Reviews

4Very nice

My travel was good..Very good experience.. nice flight and hotel..thank - Anjum  Mar 23, 2019
3Snow storm!

my tripp went well except for the cancellation of my flight from Toronto to London due to weather conditions, a winter storm, I had to book and pay for a shuttle from Toronto to London because I had to get to work the next day. Westjet offered me a flight the next day at noon. This was not workable for me. - Timothy  Mar 01, 2019
