The conversation most probably takes place [originaltext]M:Flight reservations,

M:Flight reservations, can I help you?
W:I’d like to book two seats to Alicante on a flight leaving this evening, please.
M:There aren’t any direct flights, madam. You’ll have to change in Madrid.
W:That’s all right.
M:There’s a flight leaving Heathrow this evening at 6:10, and there are two seats available on that.
W:Fine.
M:I’ll just check the connecting flight. I am afraid all seats on that flight have been booked for tonight. The next one is tomorrow morning, leaving Madrid at 10:40.
W:All right, can you reserve two seats on the flight from Heathrow tonight, with the connection in the morning?
M:Certainly. What name, please?
W:Mr. and Mrs. John Laing.
M:Two seats for Mr. and Mrs. John Laing on Flight BE 486, leaving Heathrow at 6:10 tonight, and two seats on Flight IB 240 to Alicante, leaving Madrid at 10:40 a.m. tomorrow. Has Mr.Laing got a num ber where we can contact him if necessary?
W:Yes. His office number is 542 6378.
M:542 6378. The tickets should be collected at least forty-five minutes before departure this evening, madam.
W:All right. Thank you very much.
