Translate the following English sentence to French:
"However, given that we arrive in Paris at 1.20 p.m. and the plane for Strasbourg leaves at 1.30 p.m., it is not acceptable to have a situation where, if the Madrid-Paris flight is delayed, we are left behind."
Mais il est inacceptable que si le vol Madrid-Paris prend du retard - nous sommes arrivés à Paris à 1h20 et l'avion pour Strasbourg partait à 1h30 -, on nous laisse à terre.
