I've just returned from Nairobi having flown PE with Virgin ex LHR. On all points VS won over BA WT+ (once experienced, not to be repeated). Dedicated Fast Bag Drop, priority boarding, smiling cabin crew waiting with bubbly or fresh juice, the meal very good and the seat comfortable enough that I slept for 6 hours both ways (these elements present on departure from both LHR and NBO). Feeling pretty spoiled now
