we have booked a flight from ryanair to Frankfurt Hahn airport at 6:15 a.m. on Sunday, 6th April. We don’t know what kind of transportation we need to take so early. According to the explanation on the website of Madrid airport, the subway starts operation after 6 o ‘clock, which is too late compared with the check-in more than an hour earlier. Who can teach me? Even booking a hotel near the airport… Thank you very much!
