Need info on Denver-Frankfurt-India Lufthansa flight
 

Hey, So i just booked a lufthansa flight from Denver to New Delhi. I hold an American Passport and I have a recently approved Indian E-Visa for 1 Year.
I am fully vaccinated along with a booster dose i got recently.
My questions are:
Do I need a COVID test to transit via germany? For India I don't but want to confirm for Germany.
Will the CDC vaccination card work? Also the vaccination card has Middle initial only, not the full middle name, by standard format. Although everything else - passport, ticket and visa have exact full names.
I have booked an onward flight to bangkok, from delhi. Will that be a suitable proof of onward travel at departure check in? I hope they do not expect a return ticket all the way back to USA.
Is 2 hours of connection time at FRA enough?
Thanks in advance!

If you travel on 1 ticket and with a transit in FRA, you will not enter Germany and do not need to fullfil German Covid requirements. You will be asked to show Covid documentation at check-in.
Most likely the check-in agent will not be interested in your onward journey. Just have your DEL-BKK ticket/e-ticket receipt ready to show at check-in or immigration in India, if needed.
2 hours at FRA is more than sufficient; when you are traveling on 1 ticket there is nothing to worry about. 99% chance that you will make that connection.

Do you meet all requirements to enter Thailand? Immigration officials check for this if you must prove that you have an onward journey.

For thailand the visa is on-arrival. Other than that we have a confirmed air ticket so yes we meet all the requirements of Thailand.
