Travel tips
Arrive early for domestic flights
TSA generally recommends arriving at least 2 hours before a domestic departure, more at larger hub airports during peak travel periods.
Pack a mixed carry-on
Keep a change of clothes, chargers, and any essentials in your carry-on rather than only your checked bag, in case of a delay or a bag that doesn't arrive with you.
Ease jet lag on longer routes
On longer cross-country flights, adjusting your sleep schedule a day or two before departure and staying hydrated in flight can reduce jet lag on arrival.
Screenshot your confirmation
Save a screenshot or PDF of your booking confirmation and boarding pass before you travel, in case you lose signal or battery at the airport.
Check in online when it opens
Most airlines open online check-in 24 hours before departure — checking in early can help with seat selection and, on some airlines, boarding group assignment.
