Back-to-back ticketing is verboten because it circumvents airline fare rules. For example, a back-to-back ticket may be used to circumvent a Saturday night stay requirement, a Saturday night stay usually being the difference between a cheaper fare offered to leisure travelers and a more expensive fare targeted at business travelers.
The only way to do Back-to-Back without getting in any trouble, is very Simple, You book 1 tkt on CO and the other on UA. The only problem is you wont beable to get the credit for both trips on 1 Carrier.
A Genius of a friend that I advised thusly , went out and did say a UA and USAir and had the US miles also go onto their Mileage Plus acct, you got they were Caught. Lesson is is does NOT pay to be GREEDY. BTW I did tell them it would be Foolish to risk it , but they knew better
