5My Paris /London trip

Even though I booked my Multi-city Toronto to Paris and then London to Toronto flight the Friday before my Monday departure, everything went smoothly. The phone agent never tried overselling. he gave me easy direction on the website. and communication was 100 %. Amazing vacation visiting my family. Already looking forward to booking my December trip Love you, you guys...!!!!! - Christopher  Aug 19, 2019
