Just booked our April flights and was surprised to find a Philadelphia to Orlando flight for $51. This was for a 4:50 flight on Saturday, April 18th. Played around with a couple of other dates and found that quite a few of the later flights were also under $100. Another flight on the 18th (3:50 PM) went down to $51. We are returning on May 4th and there aren't any $51 fares on that date. However, checking the 5th, 6th, and 7th, there was at least one flight per day returning to Philly that was $51. Round trip fare of $102 from Philly is unbelievable.
