G-OOBK/BL/BM, DBLA, PJLO are all in the same config, 258 pax, 63 prem, 195 economy in a 2-3-2 config
G-OBYF/YG/YH & sometimes SE-FRS (a Tui Nordic aircraft registered in Sweden used by TOM in the summer) make up the other 2 configs as they swap between the 2 depending on whether the aircraft is planned in advance of a long haul flight, the long haul config is 283 pax, 31 prem 252 economy with 2-3-2 in prem and 2-4-2 in economy. the shorthaul config is 328 pax in an all economy 2-4-2 config. It is possible in certain situations for the 328 config to operate LH to cover technical problems etc.
Currently there are 2 aircraft operating as 328 & 1 as 283, with SE-FRS being used as a STBY aircraft in a 328 config in case its need for SH
