Question 81 - 82 refer to following paragraph:
From: Rachel
To: Sophie
As per our telephone conversation yesterday, I’m sending you the schedule for Mr. John Lehman’s business trip. I would appreciate it if you could book the flights and hotels based on this itinerary. Since he has several meetings scheduled in each city he visits in Europe, please note that Mr. Lehman must take early flights for all of his departures except for the New York to Berlin flight. He has an important lunch reception in New York on May 10 , so the earliest time he can depart is 3 p.m.
May 10: New York to Berlin
May 13: Berlin to Barcelona
May 15: Barcelona to Madrid
May 17: Madrid to Firenze
May 20: Fienze to New York
Based on the information you have given me, I informed Mr. Lehman that there is no direct flight from Firenze to New York that fits his schedule. Therefore, please make sure that he has at least three hours to transfer so as not to miss his connecting flight due to any possible delays. Also, Mr. Lehman would like to change planes in Barcelona, if possible.

If you have questions or concerns, please let me know right away. Thank you for your assistance.
81. What does Mr. Lehman want to do?
