Reliable, Trustworthy Travel company

I booked all my international travel arrangements with Travelstart for the entire family. They always send great promotions and are very reliable. However, sometimes they advertise flights at very low prices and when you look to book it, you can't find it. So they say it may be for other dates, and ask what dates we want to travel. Instead they should specify which dates are the specials for as it can be very frustrating when you search for the "offers" they are promoting.
