Booking system is now "working", and when pricing up on elal.com for 'UP' destinations from April onwards it redirects you to the 'UP' website!
However, these are the prices I'm getting for May...
TLV-LCA-TLV - $1980 for Basic or a Smart fare can be had for a bargain $3870!
TLV-TXL-TLV - $523 for Basic and a whooping $1273 for Smart.
TLV-BUD-TLV - $257 for Basic and $843 for Smart.
I haven't checked the other destinations, but it's pretty clear they've gone live with the wrong pricing which is ridiculous.
