This post is a brief checklist of international travel preparation during the COVID-19 pandemic during Fall of 2021. We took the trip on October, 2021 from Atlanta, USA to Southern Europe. The trip involved a week-long cruise in western Mediterranean from Barcelona, Spain. Then a week long road trip around the French and Italian Riviera. Please note that this article is specific to post-pandemic travel in 2021. Travel restrictions in 2022 and later have changed.
A cruise and a road trip have different pros and cons and we wanted to experience both during pandemic times. A cruise allows you to relax without worrying about hotel and transportation while travelling to various countries. However excursions maybe limited and the experience restricted. A road trip will require you to find suitable accomodations but we found it less restrictive driving a rental car in Spain. France and Italy.
PREPARATION

2 weeks before departure : Confirm Flight Booking – due to ever changing pandemic rules many flights are frequently cancelled. Make sure to confirm your booking with your airline 2 weeks prior to departure.
Luggage planning – check luggage allowance policy of your airline and any connecting flights such as carry on and checked in luggage limit.
10 days before departure : Complete Advance Info online Your airline would typically have an Inquire Form questionnaire or similar item that you can feel online to make check-in smooth.
