Changed or not yet changed, why take the risk: Just booked EWR-BRU with CO BF, for just under $1700 RT while (inferior) Envoy from EWR (Thru PHL) is $4745 RT !!! Since my wife and I are both flying a huge savings.
For the record, directly from PHL, it is only 5131.-!
Flying US for convenience locally, but internationally given up some time ago, and unlikely to try in the near future until there are consistent stories about a business class product comparable to CO, NWA and such.
