So even if he has a certain date I mind. And he cant see available flights That are actually available. Op has stated that flights are available but not showing up (unless he has edited)Then as I have clearly indicated the OP should try different dates. The OP is not correct in indicating there is limited availability. Id suggest that the OP has not planned far enough ahead hence why all of the flights have been taken.
Your sound advice is to look at different dates
Yeah right
