Dear All, During our European project SYN+AIR (Sesar-H2020) we are going to conduct an online survey which aims to collect information regarding the users’ attitudes about new future service referring to passenger #multimodal transport which should provide seamless door-to-door #transport. We are glad to invite you to participate in the survey. The questionnaire is available in English language, and you need approximately 20 minutes to fill it in. We recommend completing the questionnaire on a computer, if possible, because it is more convenient than on a mobile phone. All adults that travel or used to travel by plane can answer this questionnaire. The survey will be open until November 30th at the link https://docs.google.com/forms/d/e/1FAIpQLSc37aGrUrAoicfphgKDXcgKnjkC8D5UCUgkpUUjrtUrl8iVkA/viewform Thank you for your time, On behalf of the SYN+AIR team
