If you are connecting through a hub, allow at least the airline's published minimum connection time plus 30 minutes during winter or in known-bad-weather seasons.

Booking & check-in tips

• Book directly on the airline website. Third-party agencies often charge service fees and complicate any future change request.
• Check in online the moment check-in opens (most carriers open 24–48 hours before departure). Late check-ins are first to be denied boarding when a flight is oversold.
• If your fare allows free seat selection, do it early. Mid-cabin window/aisle pairs go fast.
• Sign up for the loyalty programme even for a single trip. Many carriers waive change fees or offer faster rebooking for members.
