I see the need Paul Lupp but no app would be up to date as the number of sources that can book a particular flight are myriad. It only needs one sports team to book in 30 seconds after you have looked at it ... bear in mind that, nowadays the carrier's computers aim for each and every flight to be 100% full. If there is only one rotation a day, that means the carrier cannot justify a second and might, as we read above, simply swap the equipment to cope with a strong demand. This could be for a festival, convention or sports event at destination, that might only happen once a year. There is no telling.
