It seems like, when ever you hit page, this send you an email. To avoid this issue, you can check form is posted or not.

Example

function booking_mail()
{

    if( isset($_POST['txtemail']) )
    {
        $txtname= $this->input->post('txtname');
        $txtcel= $this->input->post('textcel');
        $txtemail= $this->input->post('txtemail');
        $txtmessage= $this->input->post('txtmessage');
        $destination = $this->uri->segment(3);
        $fare = $this->uri->segment(4);

            $this->load->library('email');
            $this->email->from('turkishairlines.com', $txtname);
            $this->email->to('fantastictravelsuk@gmail.com');
            $this->email->subject('Turkish Airline Booking Form');

            $this->email->message(
            'Name: '.$txtname.'
            Cell No: '.$txtcel.' 
            Email: '.$txtemail.'
            Message: '.$txtmessage.'
            Destination: '.$destination.'
            Fare: '.$fare.''
         );
        $this->email->send();

            $this->load->view('thanks');
    }
    else
        die('form is not posted');

}
