Answer 1

On trouve aussi quand le nom ou quand trough-ticketing vient modifier system/service : « transport avec billet de correspondance » (Termium).

Answer 2

Several sources would use billet direct in French to convey the meaning of the through ticket. Sometimes the term billet direct combiné is also used to signify interline change (source: TERMIUM Plus, The Government of Canada’s terminology and linguistic data bank).

References:

1. 2021/C 68/ 01. Position (EU) No 1/2021 of the Council at first reading with a view to the adoption of a Regulation of the European Parliament and of the Council on rail passengers' rights and obligations. in Official Journal of the European Union, C 68.

(9) ‘through-ticket’ means a through-ticket as defined in point (35) of Article 3 of Directive 2012/34/EU;

with the French version of the same document:

9. «billet direct»: un billet direct au sens de l’article 3, point 35), de la directive 2012/34/UE;

2. Similarly, in the opinion (IMCO-AD-619085) on a similar question (English / French):

... This opinion therefore contains a clearer definition of through-ticket and a proposal to set up online programming interfaces (API's) through which railway undertakings shall provide non-discriminatory access to all travel information, including real time operational, timetable and tariffs data. In order to give passengers the possibility to make an informed decision when purchasing tickets through a duty for ticket vendors and railway undertakings to inform passengers when the price of a so-called through-ticket substantially varies from the accumulated prices paid when buying tickets separately from the different operators.

is written in French as follows:

... Le présent avis contient donc une définition plus claire du billet direct et une proposition concernant la mise en place d’interfaces de programmation en ligne (API) à travers lesquelles les entreprises ferroviaires devront fournir un accès non discriminatoire à toutes les informations relatives aux voyages, y compris, en temps réel, des données opérationnelles sur les tarifs et un calendrier. Pour que les voyageurs puissent acheter leurs billets en toute connaissance de cause, les entreprises de vente de billets et les compagnies ferroviaires doivent avoir l’obligation d’informer les passagers lorsque le prix d’un billet direct diffère considérablement de la somme des prix payés en cas d’achat séparé des billets qui le composent auprès des différents opérateurs.

Therefore, at least in the European Union, the term billet direct is used quite often in the legal sense.
