Currently the last available Monday outbound flights on both Monarch and Easy Jet is the 23rd April though Easy jets Wednesday service continues till the 20th June.
This will then leave only Egypt Airs flight from London Heathrow as the only direct service to Luxor on the day when most of the UK Nile Cruises start their service.
It seems the reason for the cancellations is pure commerce, ie the flights were not selling sufficiently well to make the route profitable and with the Egyptian Tourism board seemingly not in a position to offer any support this will create further problems for a market still struggling to recover after the events of 2012.
Thomson's Wednesday flights from both London Gatwick and Manchester will still be operating but with most of the UK Boats, The RA II being one of the exceptions, operating a schedule where they have already sailed from Luxor it remains to be seems what this will mean and how it will effect tourists who have already booked a Nile Cruise holiday.
