Yesterday at work, I booked a honeymoon couple from Detroit to Maui in June on Funjet vacations. Funjet has contracted fares with United, and always offers a good price. I booked the morning flight from DTW to ORD and then booked the connecting flight....UAL Flt 3 from ORD nonstop to Kahului, Maui (B777). After booking their hotel and rental car, the return flight selections came up. I was quite surprised to see that the return flight from OGG to ORD was....UAL Flt 3...one stop. I thought that there might be a error in the system, so I went to SABRE and brought up the intinerary for UAL 3.....ORD-Kahului-Kona-ORD. I am assuming that it is the same aircraft for the entire trip.
I'm wondering if anyone knows of other current flights that leave a certain airport, stop at one or more destinations, then return to the origin airports while retaining the same flight number for the entire flight. I think it happened on occasion years ago (PanAm's round the world Flt #1 started and ended at JFK), but it has been some time since I have seen this. Thanks.
