This campaign is part of the partnership bewteen the Castellon airport and Air Nostrum. The aim is to stimulate connecting traffic thanks to the Castellon-Madrid route launched in October 2022, but also to bring more tourists to Castellón and the Valencian Community by air. Note EC-NHU has the full IB Regional/Air Nostrum scheme while EC-NLM initially only had an incomplete white scheme with the special stickers. A CRJ-1000 joined the party in 2024.
