I have collected enough frequent flier miles in my life to get a pretty decent "view" of many different programs. I recently tried to book my honeymoon using miles to upgrade a purchased coach ticket to First Class.I was both surprised and disappointed to learn that Continental Airlinesmakes it VERY hard to do such a thing. They will not confirm you in theirBusinessFirst class right away, like most every other airline I know do.You must purchase your ticket, and then go on a waiting list. Their isabsolutely NO guarentee that you will be upgraded. Furthermore, if youwished to use your miles to get a free BusinessFirst ticket to Europe(100,000 miles), you cannot do that until 30 days prior to departure.Thus, planning a trip in advance using your OnePass miles is virtuallyimpossible. When I discussed this with a supervisor, she even agreed thatas a policy it is often unfair. When I called TWA and Delta, they wereable to confirm me right away if I had the miles and wanted to.
