Why would the speaker like Barbara to contact him?

Question 45 - 47 refer to following paragraph:
Hello, Barbara. This is Jim Michael. I’m calling with regard to the change you had asked for in your travel plans. I’ve looked into various flights from Calgary to Honolulu and Jet Quest Airlines is the only one that connects in Los Angeles. A stopover flight is actually $50 less than the original price that I had quoted you, so I have reserved a seat for you on that flight. Please check with your secretary, as I have faxed the new itinerary to your office. Also, please send me an email should you wish to book accommodation in Los Angeles. I have found a few hotels in the downtown area, but I’m unsure of your price arrange. I look forward to hearing from you soon.
