I plan to purchase a Lufthansa return air ticket, from New Delhi, India, to Mexico City this May. The departing flight has a 5h 50m layover in Frankfurt and the returning flight has a 7h 10m layover in Munich. So, the itinerary is Delhi-Frankfurt-Mexico City and Mexico City-Munich-Delhi.
I have a Bangladeshi passport, with an Indian visa and a Mexican visa. I am planning to apply for a German transit visa (Category A).
I have read that I can't use this category of German visa if I have to pick up my baggage and/or have to check-in again at the transit airport. Will I be able to travel without trouble with these travel documents on this Lufthansa flight? That is, does Lufthansa provide adequate support at the departure/transit terminal to make sure that I don't need to leave the international transit area, stay air-side and don't need to pass through border control/immigration in transit?
And also, is it easier to get the ATV than the usual Schengen visas? I emailed the consulate and they replied that I don't need to submit any financial documents. Hence, I think it should be rather straightforward, right?
