What Our Students Say

CAMILLA - 2ND STEWARDESS

I am absolutely thrilled with the Crew Wellbeing and Human Resources Course! I truly loved every aspect of it.

The course was exceptionally well-organised, combining videos, written content, quizzes, and assignments they made the learning experience, engaging and comprehensive. I appreciated the supportive atmosphere; I never felt hesitant to reach out for help. Everyone I worked with was incredibly helpful and encouraging. Overall, this course was genuinely amazing, and I am excited to apply everything learned onboard!

OLIWIA – CHIEF STEWARDESS

I found myself looking forward to each new lesson, and although it cost me not one but a couple of late nights, it was totally worth it!

The passion from TYSA and its community truly shines through, making my learning experience even more enjoyable! I’d like to highlight the outstanding support and responsiveness I experienced throughout the course!

MAJA - SENIOR STEWARDESS

The Destinations, Events & Interior Management course covers all areas related to HOD responsibilities, making it suitable for professional senior interior crew. Content is in various formats, and realistically applicable to an Interior Management role onboard any program.

Instructor feedback was personable, and I also appreciate the fact that TYSA truly valued student feedback, introducing a platform for course-specific student community & networking upon our requests. Thank you Gemma and the team for being so passionate about training and leadership in this industry. Genuinely recommend the course!
