I recently missed a flight which I'd booked through Carlton Leisure due to numerous delays at the airport. When I contacted them to inform them about the situation and ask if they would support with the re-booking, they told me it was impossible due to their policy on "no shows", and that I would have no choice but to re-book the tickets myself at a massive additional cost. Later, I discovered that the policy they quoted doesn't actually appear in their Terms and Conditions at all. I asked them nine times by email to ask them to confirm if that was the case, and every single time they avoided answering the question. Eventually they stopped responding at all, which is incredibly unprofessional and unhelpful. If you're considering booking your flights through Carlton Leisure, do yourself a favour and book directly with the airline instead. You'll have far more consumer rights should something go wrong, and you won't have to deal with unprofessional customer support staff quoting policies which you were never actually shown when making the booking.

One of the worst experiences. Do not use this company!
