The group's shares, which have sharply under-performed, rose 22p to 596p. They are still a long way below the 760p achieved nearly a year ago but have at least climbed from the 499.5p low hit last month.
BA and its proposed US partner have battled long and hard and, for a time perhaps too belligerently, to win approval from the Eurocrats of Brussels. Close observers feel that after months of uncertainty the airlines have started to decisively win the argument and the EU may demand only modest concessions. The Brussels decision could be known in the next few weeks.
The proposed alliance has been under scrutiny for nearly two years with many airlines objecting to what they saw as the creation of a far too powerful competitor.
The rest of the market experienced a typical pre-Budget session with trading volume again inflated by bed and breakfast deals. Footsie ended modestly higher, 2.8 points at 5,785.1, with the mid and small caps indices again stretching to new peaks.
Cadbury Schweppes was one of the few Footsie constituents to reach a new high. The shares rose 16p to 833p with the market taking an increasingly positive view of the soft drink to sweet group's US prospects.
It splashed out pounds 1.6bn for America's third largest soft drink group three years ago. The last trading report was upbeat and Cadbury's reduced its dependence on US bottlers, some owned or related to its big rivals, Coca- Cola and Pepsi Cola, by taking a minority interest in a bottling operation.

Tesco gained 7p to 538p with SG Securities suggesting a 650p target. Zeneca, off 99p at 2,600p, and SmithKline Beecham, 20p to 737p, were hit by Goldman Sachs caution. Hanson, the building materials group, hardened 13.5p to 365p following a Panmure Gordon push.
Publisher Reed International gave up 21p to 578p as Cazenove placed 5 million shares.

Dixons, which is losing its Footsie place, fell 6.5p to 472.5p, Boots 11.5p to 898.5p and Next 8.5p to 725.5p. DFS Furniture, off 14p to 415p, and Debenhams, 9.5p to 371p, were among other losers.

Hunting rose 7p to 236.5p on the pounds 24.7m sale of its largest aviation business. It intends to concentrate on its oil operations.
Tele-Cine Cell, a special effects film and video group, firmed to 71p. It is in talks with Todd AO, the US group, which could lead to a bid. Waverley Mining, once riding at 132p, rose 7p to 23p after recording it was in bid talks.
