TRAVELER FAQ
Answers before you leave.
How early should I arrive?
Use the operating airline and airport's current instruction for the exact flight and add the traveler's own luggage, mobility and unfamiliar-airport margin.
What identification do I need?
Check the operating airline's current domestic passenger identification rule for the traveler's status; do not infer it from another passenger or route.
What if weather affects the flight?
Follow the airline and airport's live status and rebook only through an authorized channel. Recalculate the onward route before accepting a replacement.
