To be honest, I don't know. It would also make more sense to me if it was the other way around...743s for the TFN
flights and 744s for the MIA
About their cabin configurations, the 743s were initially fitted with 100% Iberia interiors (F/C/Y seats, curtains, cabin dividers, etc) when they joined the fleet in late 2000/early 2001, being the the upper deck used for First Class, the first and second lower deck sections for Business Class, and the remaining sections (3,4,5) for economy. These aircraft have not and will not recieve the new seats/cabin configuration (Business/economy...no First Class anymore) that is being applied to the entire A340-300/600 fleet as they are supposed to leave the fleet soon.
The 744s feature an all-economy class lower deck and Business Class seats on the upper deck and they did not recieve any change to their cabin interiors when they joined the fleet. They feature the same seats they had when flying with their previous operator (SQ) and only seat covers with the IB
cloth colors were installed. That's why you will see that these aircraft feature PTVs in economy class although in IB
they only show the same program that is being shown on the main screens.
That could be a reason for the route assignment...the 743s cabins are better configured for long flights.
The 744s are mainly used on the MAD
flights although they have also operated flights to MIA
when a replacement aircraft has been needed.
Both 743s (TF-ATI and TF-ATJ) were originally delivered brand new to Varig in 1988 and were registered as PP
-VOB and PP
Varig used them until early 2000 when they went to ILFC for just a few days before going to Air Atlanta.
The 744s (TF-AMA
and TF-AMB) were originally delivered brand new to Singapore Airlinres in 1989 and were registered as 9V
-SMC and 9V
As you can see, the 743s are only 1 year older than the 744s.
I have flown on all of them (TF-ATI, TF-ATJ, TF-AMA
, TF-AMB) and if you want my opinion all of them don't look well kept on the inside, with the 743s looking worse.
That's a big contrast when compared with the A340 fleet.
should do if they really need an aircraft bigger than the A346 for certain routes (forget the A380..it would be too big) is to BUY
a few used 744s, put them into the hangars for a couple of months and overhaul them completely, also replacing all their interiors with new elements (777-looking interiors as those featured in the 744ER would be great) and installing the new seats that are currently being installed on the A340 fleet...just my opinion.
