We received BOGO flight for Quebec City to Boston cruise 10/4. ( 2 day deviation ) I have been waiting and hoping for a good flight. Great times, leave COS @ 6:04 am to CHICAGO to Montreal arriving at 2:25. Return flight leaves Boston at 12 layover in Denver and home by 4:30. On United web prices today shows economy @ $4249 each. Must be a glitch for other flights are around $400-1700 range. This best flight since we have to get to Quebec City by train. Very happy with flights.
