No idea why the header in the end is not redirecting to the thankyou.html page. I read similar previous posts but in most case people were simply using echo() instead of header() or something like that.
<?php
if(isset($_POST['submit']))
{
$email_us = "info@pureazorestours.com";
$email_user = $_POST['email'];
$subject_us = "Website Reservation";
$subject_user = "Reservation request recieved";
$fname = $_POST['fname'];
$msg_us = '
