A lot of people on FT claim they couldn't possibly endure a narrowbody transoceanic flight, which is pretty funny because they were commonplace for decades, through 1980 or so. There's really no difference in individual comfort compared to the widebodies, and you get to circumvent big difficult hubs in Europe. CO opened secondary markets like BRS, BFS and EDI direct from EWR and, before EWR went totally to hell, it was a definite net positive to fly a 757 out of there to those small markets and avoid transiting LHR.
