I don't know why PASCAN is misreading the local market so badly.
Both St. John's and Quebec City would be popular destinations from Moncton.
There are a lot of ex-pat Newfoundlanders in and around Moncton and CanJet had a successful direct flight to St. John's (before the airline scrapped it's regularly scheduled service and became charter only). It was a 737 service and had pretty high passenger loads.
Similarly, for obvious ethnocultural reasons, a direct flight from Moncton to QC makes a lot of sense. I could see this being very popular with francophone academics, students, business people and politicians. Priced properly, there could be some tourism traffic as well.
But with round trip prices of over $700 to QC and over $800 to St. John's, these flights will never catch on with the broader public.
This service will be gone within the year, which is a sad thing because properly priced and marketed and with a reliable mainstream operator, both these services could be successful.....
