Excel Airways
I am surprised at your comments regarding the attitude of Excel Airways Cabin Crew as this is far from my experiences with this airline. Having taken 4 return trips with XLA over the past 18 months or so, without exception the crews have been polite, friendly and efficient.
Regarding your comments on aircraft comfort, I sympathise with your situation as the B767 in 2-4-2 charter configuration is an extremely uncomfortable aircraft. This however, is by no means exclusive to Excel Airways.
Prior to booking a flight with any airline, I always check the aircraft type and give B767 in 2-4-2 configuration a miss.
