MUC city day ticket and carry-on cooler bag
I'll have two long overnight layovers at MUC this month. I'm planning to purchase an airport-city day ticket to go into the city, then purchase an one-way ticket back to the airport the next day. Should I buy the ticket online or wait until I arrive at MUC? Also I might have to bring some prescribed medicines that requires refrigation. Has anyone encounter problem check small travel cooler bag w/gel ice packs as carry-on? TIA.
