Perhaps you answer your own question.
If Delta are not cutting theirs back this winter as before, then this may have forced Uniteds hand, if during this period yield is marginal.
BHX only goes down to 5 a week for 1 winter month and is 6 a week for the rest. BHX is not mentioned in the press article but could easily get suspended also.
Not sure Ive heard of a US carrier suspend services for just 9 weeks before ?
