Airport Information & Terminals
DEN: Denver airport. Denver airport transfer should be matched to the exact hotel, suburb or meeting area. Rail can work well for light luggage, but late arrivals, winter weather and family baggage often make a direct cab or booked transfer easier.
BOS: Boston Logan International Airport. Logan is close to downtown Boston compared with many US airports. Taxis, airport buses and transit work well, but winter weather and academic move-in dates can change travel ease.
