OK, you want widebodies - Here you go:
B767-200/200 - American (from April 2nd), Airtours, Britannia. Sometimes HY (covering for 757)
A310 - Cyprus Airways, Air Transat
A330-200 - Emirates, JMC, possibly Airtours/MyTravel
Lockheed L-1011 - Air Transat
B747 - PIA are supposed to returning in April with X2 747's via FRA
Some of the above only operate in the Summer season. BY fly the 767-300 to Orlando from BHX in the Summer, they seem to get off the runway OK.
While it is true BHX suffers due to it's main runway, it is 2606m in length. Similar to airports such as Glasgow - Yet you don't hear people slagging GLA off due to it's runway length. Strange that is...
We used to get regular DC-10's during the Summer with the likes of MON and JMC, but they've all stopped flying these a/c now.
