Low airfares, but does not provide time of arrival.
Change the date of departure and arrival by one or two days. Often, this can make a huge difference in the airfare. Some airlines have lower rates when you fly on weekdays and some when you include a Saturday night stay. We do offer the ability to extend your trip by 1-2 days after or before your tour just for this reason (please check in advance for availability of extra days). You also have the option of arriving early or staying an extra day and doing some sight seeing on your own. Airline fares can change in an hour, prices often go down as well as up 60, 30, 14 and 7 days prior to departure. If you don’t live too far from other major cities, it’s worth checking airfares from other nearby departure cities.
