Booking Discounted First Class Fares?
First Class fare searches on agency and airline sites (other than FareCompare.com) hide the first class search under their advanced option section. Look for the link that says “Advanced …”, “Expanded …” or “Additional …”, select the “Business or First Class Cabin” option and issue the search. Compare the first class price with the coach price. Beware of Flights without a First Class Cabin Connecting flights may have a portion of the trip on a plane without a first class cabin and online agencies and airline sites will sell you Y-Up fares on these flights (even though no first class cabin exists on the smaller planes). Make sure all flight segments you chose have a first class cabin!
