A follow-up to the discount fares Westjet began offering in May, the end of season flights to Dublin from St. John’s, Newfoundland are now even lower, down to $450 return for select dates in October. Edit: A shorter trip date combination dropped even more the next day, now down to $421 !
Halifax can also take advantage of this sale, the lowest I spotted was $508.
(quote shown for YYT departure October 13th returning October 16. Returning on the 22nd still only $450)
