Air Transat Route Network
Air Transat’s network centers on leisure travel from its Montreal and Toronto hubs, spanning sun destinations across the Caribbean and Mexico plus an extensive transatlantic network to Europe, North Africa, and beyond.
Primary Hub
Montréal–Trudeau International Airport (YUL)
Montréal–Trudeau International Airport (YUL) is Air Transat’s primary hub, with Toronto Pearson International Airport (YYZ) serving as its second major base, plus focus cities in Ottawa and Quebec City.
Alliance & Partner Airlines
Air Transat is not a member of Star Alliance, oneworld, or SkyTeam and operates independently, though it coordinates connectivity with Porter Airlines on select routes through Toronto.
Baggage, Seating & Onboard Amenities
A quick reference before you pack — always confirm exact allowances on your fare rules at booking, since they vary by route and cabin.
Carry-On & Personal Item
Economy fares typically include one carry-on bag plus a personal item, with the exact allowance depending on fare class.
Checked Baggage
Checked baggage allowance depends on fare class — the lowest-cost “Eco Budget” style fares often exclude a checked bag by default, while higher fare tiers include one or more bags.
Excess Baggage Fees
Overweight, oversized, or extra bags typically incur a per-bag fee charged at check-in or online in advance — pre-paying online is usually cheaper than paying at the airport.
Seat Selection & Cabin Classes
Air Transat offers Economy and Club Class on its fleet, with seat selection sometimes chargeable on basic fares and included on higher fare tiers.
How to Find the Cheapest Air Transat Fares
Four habits that consistently lower what you pay.
Book in the Sweet-Spot Window
For most Air Transat routes, fares tend to be most competitive when booked several weeks to a few months ahead of departure, rather than at the last minute or extremely far out.
Fly Midweek and Off-Peak
Tuesday, Wednesday, and Saturday departures are usually cheaper than Friday or Sunday, and red-eye or early-morning flights often undercut peak daytime departures.
Set Fare Alerts
Track your route and let price-drop notifications do the watching, instead of checking manually every day.
Price-Tracking Tip
Compare a fixed date range over a week or two before deciding — single-day price checks can be misleading.
Compare a fixed date range over a week or two before deciding — single-day price checks can be misleading.
Use Flexible Date Search
Searching a date range instead of one fixed day often surfaces Air Transat fares that are noticeably lower just one or two days earlier or later.
Check-In & Day-of-Travel
Online Check-In
Online and mobile check-in generally opens 24–48 hours before departure, letting you select or confirm your seat and download your boarding pass in advance.
Airport Arrival Times
Arrive with enough buffer for check-in, bag drop, and security — this matters more on international Aegean Airlines routes than short domestic hops.
Domestic vs. International Cutoff
International check-in and bag-drop counters usually close earlier relative to departure than domestic ones, so double-check your specific route’s cutoff.
