I just checked the flight that it is now scheduled to arrive into Toronto at 7.32 pm, can I safely assume that my relatives are going to miss the connection flight to Houston? They can only read some English in writing but only speaks Mandarin and Taiwanese. Do you think I should call Air Canada and inform them about the possible missed connection? My relatives have eTA and able to enter Canada if needed.
This was a last minute booking shortly before Christmas, the ticket they are traveling on right now costs only half of (or less if on Singapore Airlines) other 1-stop options. Moreover, they prefer 2-stop en route due to shorter flight duration each. All 1 stop options, other than the super expensive Singapore Airlines one, involving at least a 15+ hours flight that they try to avoid for medical reasons per doctor's advice.
