UI/UX Design Challenge

I was asked to complete the brief below as part of a UI/UX technical design challenge:

Objective
Produce a home screen design for a travel booking app.

Requirements
Consider how you can make it easy for users to search for hotels, flights, cars, and activities. Consider how you can make it easy for users to review their past and future bookings. Consider tailored experiences for a guest user and a logged in user. How can you make the app more personalised for the latter? You will be required to display a call centre phone number, 1800 TRAVEL, somewhere in the design.

Additional Requirements
Please use the brand colour #0ec697 in your design. You have complete discretion over how much of that colour you use. You have complete control over the UI of the home screen and are encouraged to think outside the box with the layout and look and feel of the different interface elements. Please produce one design for iPhone only.
