LOT almost had a dual engine failure on a 788 last year (LO-6506 Cancun Warsaw on Mar 23rd 2018). Lost one engine SW of Bermuda, decided to divert to KJFK instead of KMIA due to operational reasons (passenger visa). 2nd engine surged during the diversion. After landing at KJFK both engines had to be changed.
LOT internally clarified the definition of „nearest suitable airport“ afterwards.
