Ok, I figured I'd look into how your'e using your fleet a bit. I've got a few more points to hopefully assist your thought process(es).
1. Using 762s on routes that can be covered by 737/A320/MD/757/etc planes is typically not a very good idea. They seat 210 pax and burn fuel like its going out of style. A 757 will carry 201 pax in a 15/186 configuration and do all of those routes just as well for less per trip. An A321 should be about 15-174 if memory serves correctly and burn even LESS fuel per trip. Usage of the 762 for the US flights that you have simply isn't advisable as fuel prices increase.
2. Typically, when you have a high cost per seat plane like the 762, you'll want to match it with high revenue per seat routes, such as those with heavy premium demand. Looking at LFPO and LPPT, they barely have 10 C demand per day. That means your C cabin is 50% full on a good day. For that length route in the 762, it needs to be full if at all possible. Ideally, you'll want the 762s on routes where you can reconfigure them to capture more premium revenue, as that will boost their profitability.
Very true. Believe it or not, (regarding point 1.), I really did consider my options and took 752/3s, 320 family and the most likely of all, the 737s into consideration.
Unfortunately at the time my firm was established, there were hardly any good ones or non at all and as for brand new??? I was and still am looking at a looooooong wait. Maybe not for the !B757s but even they will have to be replaced by more fuel effient a/c and at the time there wasnt enough on the used market for 'fleet commonality. To make matters worse, I already had competition @ Piarco. So, afraid that he/she would create much more revenue than me and expand to the point where (for the limited choices of aircraft I had) I couldnt find routes without them being there (and lets not 4get one of the most important rules about new airlines and competition) I had to avoid him.
The only way of doing that AND being able to outgrow him was to tap into the European market. There is heavy competion at some destinations but I found a few untouched. So the next Q was...what can fly there? In the end, considering that there were (not alot but) a few B762s avail', I chose them. Also, the reason I decided to attack the North American routes with the 762s was for two reasons; 1. Fleet Commonality and 2. They would generate additional income until the 737s and 190ARs arrive.
Now however, (and this is why I can't thank you enough for your realistic impressions), I am going to really consider ordering long ranged B767-300ERs to replace the 762s and chase after Europe, the West Coast of USA, Africa and Asia markets. Maybe even 764s.
Just one thing tho, I am a RR fan and would choose RR over GE any day (although I do Looooove the mighty GE90 series). So I would rather have the RR RB211s and Trent1000. My concern now is when and how do I convert. And add even MORE stress, why did i go and lease my first 3 Boeing 767-200s than were averaging 15 years....for ANOTHER FIFTEEN YRZ? So it looks like unless I have the money to buy and sell or just terminate, i gotta choose GE : (
