Seems like BHD is just having a bad run!
G-TTNG went tech sometime between arriving on Sunday evening and ahead of Monday morning's departure. It is now due to head back to LHR this afternoon as BA9278 (positioning flight)
The BA1414/1423 LHR-BHD-LHR rotation this morning was due to be operated by G-EUPO, but was cancelled in both directions (G-EUPO is still in LHR), so could be a tech or ATC cancellation.
