Hello,
Thank you for contacting WP Travel team!
Actually, all the functionality of the WP Travel plugin should work fine with the Elementor page builder. However, there may raise some minor layout issues. To enhance your experience using WP Travel with Elementor, we have a separate WP Travel Gutenburg & Elementor blocks plugin which is free to download. Using this plugin, you would be able to insert several Elementor WP Travel widgets and Gutenberg WP Travel blocks.
For detail assistance regarding how to manage the trip page using the WP Travel Gutenburg & Elementor blocks plugin, please refer to the below-given link:

Also, the Astra theme is not compatible with WP Travel plugin. When using the Astra theme with WP Travel plugin functionality should work fine but may raise layout issues due to incompatibility.
