From current Wizzair sales system, the below flights presently appear not to 'fit' within the Wizz program. I am guessing there is either additional flights ex-LTN yet to be announced (which might produce up to two 'based' aircraft at LTN) or there is a big program re-shuffle that we've not seen yet:
"AIRCRAFT #1"
DAY 1 AM: LTN 0600 - 0930 SPU / SPU 1005 - 1145 LTN
PM: NIL
DAY 2 AM: LTN 0655 - 1045 DBV / DBV 1115 - 1310 LTN
PM: LTN 1405 - 1805 BEG / BEG 1835 - 2010 LTN
DAY 3 AM: LTN 0600 - 0930 SPU / SPU 1005 - 1145 LTN
PM: NIL
DAY 4 AM: LTN 0655 - 1045 DBV / DBV 1115 - 1310 LTN
PM: LTN 1405 - 1805 BEG / BEG 1835 - 2010 LTN
DAY 5 AM: LTN 0600 - 0930 SPU / SPU 1005 - 1145 LTN
PM: NIL
DAY 6 AM: LTN 0655 - 1045 DBV / DBV 1115 - 1310 LTN
PM: LTN 1405 - 1805 BEG / BEG 1835 - 2010 LTN
DAY 7 AM: LTN 0600 - 0930 SPU / SPU 1005 - 1145 LTN
PM: NIL
"AIRCRAFT #2"

DAY 3 AM: NIL
PM: NIL
DAY 4 AM: LTN 1835 - 2125 TSF / TSF 2155 - 2300 LTN
PM: NIL

DAY 7 AM: NIL

...looks very much like the TSF will end up being bundled onto an aircraft operating a w-pattern through LTN (e.g. aircraft originating from KTW or similar?) but the outline "AIRCRAFT #1" plan above is very intriguing and does very much give the impression that this is the start of a whole aircraft based at LTN to come?
