The reconfigured runway at GCI now offers TODAs and LDAs quite similar to those at SEN, with LDA being only 140m less than at SEN, so I should think the A319 could operate satisfactorily on routes from UK.
The figures are:
TORA: 09/1463, 27/1583
TODA: 09/1721, 27/1799 (same as SEN)
ASDA: 09/1463, 27/1583
LDA: 09/1463, 27/1463
