The last decade has witnessed the blossoming of abortion referral networks assisting women who live in healthcare jurisdictions that limit their access to abortion services. The Abortion Support Network has facilitated abortion travel to Britain for women from Ireland, Northern Ireland and the Isle of Man. In 2019, it expanded to support women from Malta and Gibraltar. 1 Ciocia Basia, Kumpela and Abortion Network Amsterdam aid women from Poland, where abortion access is severely restricted, in travelling to Berlin, Leipzig and Amsterdam, respectively.

We focus on the period between 1975-signifying the beginning of Spain's transition to democracy from a militaristic, right-wing, authoritarian regime, triggered that year by the death of dictator Francisco Franco-and 1985, the year in which abortion was partially decriminalised in Spain. Although this partial decriminalisation did not completely end Spanish women's abortion travel, it did curtail abortion travel as a mass phenomenon, with thousands of Spanish women annually boarding charter flights to Britain, taking ferries to Morocco or crossing borders to Portugal or France in search of abortion services. 3 Abortion referral networks assisting Spanish women were knit together by antifascist and feminist individuals and groups.
