I am planning to go from London to New York in August. However, airfares for non stop are about GBP 500 with either UA, BA or VS. However, if I were to book the ticket BRU to LHR to JFK on bmi and United the price is only GBP 230, and the segment LHR JFK LHR would be the same as booking the GBP 500 rtn from LHR to JFK.
If I were not to use the BRU to LHR to BRU on the bmi part of the ticket, will the United part of the itiniary still be valid.
What are there policies on not using part of the ticket?
Any advice would be appreciated.
