Frankfurt (am Main) airport
One of the biggest issues for a megastructure - in this case, Frankfurt (am Main) airport - is that, you have to wait by the baggage belt for half an hour in order to reclaim your baggage. You’d better take the time you spend on other things into consideration, for example, getting off the airplane and walking through maze-like corridors.
Never argue with me with regards to the word “reclaim”. You may use “claim”, my answer is nothing but “I don’t know which one is correct”.
