British Airways (BA) and Unite have resumed negotiations in a bid to settle the bitter dispute that has resulted in cabin crew taking to the picket lines. The news comes as the airline announced it will increase its capacity during the final five-day strike period, which starts 5 June. BA said it will fly up to 80 per cent of long-haul and 60 per cent of short-haul flights from Heathrow. The commercial liner will also fly a full schedule to South Africa for World Cup football fans. Currently Heathrow Airport is the only BA hub that has been affected by the strikes.
