but it all reminds me of the pre-Freddie Laker days of national flag carriers and the bewidering array of controls and rules. I flew to Los Angeles in 1977 on a £200 rtn ticket and chucked the other half away (I was there for two years). Perhaps there's an industry hankering after the good old days
.
If you buy two tickets isn't that two separate contracts: guess you might breach one but how does that breach the other ?
