Design a point based loyalty reward program for Travel app

I am looking for a freelancer to design a point-based loyalty reward program for my travel app. The program will offer discounts on future bookings to incentivize customer loyalty.

Skills and experience required:
- Experience in designing loyalty reward programs
- Knowledge of customer retention strategies in the travel industry
- Proficiency in user interface design and user experience optimization

Requirements:
1. Rewards: The loyalty program should offer discounts on future bookings as the main reward.
2. Point system: The point system should be based on the amount of money spent by customers.
3. Interface design: While I do not have a specific design in mind, I have a general idea of how I want the loyalty program interface to look and feel. I am open to design suggestions from the freelancer.

If you have experience in designing loyalty reward programs, a strong understanding of customer retention in the travel industry, and proficiency in interface design, I would love to hear from you. Please provide examples of your previous work in this area.
