Front vs back is not universally better
Priorities differ for connection time, noise and proximity to facilities.
Exit rows have eligibility rules
Do not select them unless you meet the carrier's requirements and responsibilities.
Seat assignments can change
Operational aircraft swaps can override the original map.
Verify before you go. Weather, entry rules, advisories, transport schedules, prices and local conditions can change. Use this page to structure your decision, then verify the current details that affect your specific trip.
