'On The Beach' charged my wife and I a whopping £223 more for flights from Manchester(UK) to Dalaman(Turkey), than they paid to Thomas Cook for the service.
OTB charged us £532 for the return flights.
They paid Thomas Cook £420 for the same.
The baggage charge was £19 each per journey. Total £72.
They paid Thomas Cook £38 in total.
In total, there was an increase/unearned profit of almost 30% .
The moral - never ever use 'On The Beach" - not only that, they never pick up the 'phone, nor do they give you an email address.
