Can I book on SQ a OW from TLV-NYC, first leg to FRA on LH and from FRA-JFK on SQ A380??
How much miles, and Surcharges ?
Take in mind that when you book only SQ you get 15% discount,so that will be JFK-FRA 57.5k in R.
If you add on LH on same itinery you won't get the discount,so you will end up paying 75k for a OW and if you book TLV-FRA separate it will only cost 12.5k =70k.
Take in mind you could also go with air Berlin to TXL,DUS and to VIE with 'niki' and from there get to FRA it's very cheap with avios.
