DavidFlew with Turkish AirlinesDEN-ISTMar 2025
Baggage no problem, ticketing no problem. Having only one connection is a huge plus as I often have at least two.
Verified travelerFlew with LufthansaDEN-MUCDec 2024
Lufthansa was an excellent experience, everything well organized and on time. If you desire healthy snacks, that I would advise bringing them with you. This is pretty much what happens everywhere.
TressaFlew with LufthansaDEN-LHRDec 2024
Make your layover longer because you will need it for all the walking at Heathrow
Verified travelerFlew with IberiaDEN-LHRSep 2024
Coming from Denver with London as a layover you will have to go through security again
Verified travelerFlew with LufthansaDEN-FRASep 2024
I will probably try to avoid Frankfurt from now on. The airport is very complicated. Lots of walking!
MedaFlew with LufthansaDEN-FRAJun 2024
Make sure your passport isn’t expiring within 6 months of your flight. Check in online. And get an e visa
Verified travelerFlew with LufthansaDEN-MUCAug 2024
Be early rather than on time for unexpected delays. The amount of travelers during the summer can be intense
RobertFlew with LufthansaDEN-MUCApr 2024
Make sure luggage can make connecting flight. Bring small luggage of supplies in case your bags are lost or delayed.
Verified travelerFlew with United AirlinesDEN-MUCApr 2024
More than 60 minutes to change planes are better.
