Air passengers on the London-Bermuda route face major hold-ups over the next two days.Last night’s 8.05pm plane to London was hit by a 12-hour delay, with its take-off time put back to 8.30am today, according to the British Airways website.That meant it was due to arrive at Gatwick at 7.05pm today, instead of the scheduled 6.55am.As a result, the plane due to leave London at 3.10pm today will instead leave at 9.35pm, getting into LF Wade International Airport at 1am tomorrow, six-and-a-half hours later than normal.And tonight’s 8.05pm flight to London is now scheduled for 2.30am tomorrow, getting into Gatwick at 1.15pm tomorrow.
