What is the best flight path considering the French train strike
A few Thello trains have been affected by the strike. It doesn't matter that the trains are not run by SNCF, if signals staff are on strike and don't let them pass. For the status of Thello trains on strike days, follow the link on here https:/…
If Thello trains are affected on your day, you could get a bus to Menton then a taxi to Ventimiglia then take the train from there. Or, cheaper, a Flixbus bus direct to Genoa and train from there. The Flixbus buses stop at the Fanti d'Italia bus station which is a few minutes walk from Genova Piazza Principe train station.
There are no direct flights from Nice to Genoa or Pisa.
To look on the bright side, Thello trains were not affected on the last three strike days. And support for the strike seems to be reducing somewhat. So it is possible that no further Thello trains will be affected.
