Having just recovered the long-haul program following the problem with G-TUIE at Cancun I see that G-TUIC is still on the ground at Puerto Vallarta after landing 33 hours ago. PVR-LGW TOM033 cancelled yesterday. LGW-POP TOM096 operated by B763 yesterday (4 hours late) so given crew rest in POP TOM097 will not be back at LGW before about midnight. TOM052 LGW-CUN today already delayed 9 hours, no doubt awaiting the arrival of G-TUIB from MRU this afternoon. Does anyone know what's wrong with G-TUIC at PVR?
