Difficult to keep a/c that you do not own.
"NB" & "NE" were sold to Fedex a few years back and had slots for conversion booked.
Now "NC" & "ND" were also sold a few years back, but we could have had the leases extended, but costs were looked at for the checks that were coming up and the decision was made to end leases when due.
Hope to have the ex "C" check in service from LGW on Thursday.
