The money, from its £74m capital reserves, is the latest part of a £13m loan package to attract new airlines.
Airbus will get £2.7m for training facilities at Swansea University and Coleg Cambria in Deeside, Flintshire.
While transport projects in north Wales, including Llangefni link road on Anglesey, will also get £2.7m.
The Welsh government will also set up loan funds for small businesses.
Finance Minister Jane Hutt said the money would boost infrastructure priorities and deliver "real and long-term benefits for people".

The system is being based on the way people fill up their car with petrol or buy data bundles with a mobile phone.
The company says it is an attempt to simplify energy bills.
ScottishPower chief executive Keith Anderson said: "We're saying to people buy it by the day, not by kilowatts or a fancy tariff you don't understand."
Customers will use an app that has a gauge measuring consumption.
The company will tailor each customer's "day" based on a personalised forecast of how much energy they typically use.
This will also vary according to the time of year.
Customers will be able to buy packages of gas and electricity in quantities from one day to a month, and up to 180 days ahead.
The firm has been piloting the scheme and it says it could transform the way consumers buy energy.
Mr Anderson said they went back to scratch and looked at how people bought petrol for their car.
"You go to the garage and put Â£50 in your car. Inherently you know that will last you two to three weeks.
"We thought why don't we do the same thing with energy."
A fuel gauge supplied within the app will then tell customers how much energy they are using and how much they have left.
Under the scheme, called "PowerUp", customers will not have to pay a standing charge.
Scottish Power said its tariffs for the scheme would include some of the firm's most competitive prices.
It will be launched to existing customers initially, and the company firm will then consider whether to open it up to the wider market.
A two-year investigation into the energy industry by the competition authorities found that many consumers were not engaged in the energy market and failed to switch to the cheapest deals.
The new approach to buying energy has been welcomed by the industry regulator.
In a statement, Ofgem said: "We want more competition to increase choice and drive down prices for consumers.
"We encourage suppliers to offer new innovative tariffs to help people engage in the market and find the best deal which suits them.
"Innovative tariffs can be tailored to an individual consumer's needs and give people more control over their energy bill and how they pay for it."
Claire Osborne, energy expert for Uswitch.com said: "Energy bills are notoriously difficult to understand and so this approach, similar to how we buy petrol, should help consumers use less, waste less and pay less for their gas and electricity.
"The fact that the deal has no standing charge will be attractive to many customers - particularly those with second homes which are unoccupied for part of the year - as there's nothing to pay on days when no energy is used."

The Competition and Markets Authority (CMA) had ordered all insurance companies to split out the extra charges for the additional protection.
But the Co-op was the only firm which missed a deadline to do so, in August last year.
As a result around 120,000 customers received quotations that were unclear.
From 1 February, the Co-op will provide two separate quotations - one with no claims bonus protection, and one without.
"It is very disappointing that a major company such as Co-op Insurance has taken so long to provide this vital information to its customers," said Adam Land, senior director of remedies, business and financial analysis at the CMA.
"Before the order came into force, the price and benefits of NCB [no claims bonus] protection were often unclear to drivers.
"We expect the Co-op to fully comply with the terms of our directions immediately, so that motorists can search more easily for the best deal for them, and decide whether or not they want this optional cover."
The Co-op said most of its quotations do now provide separate details of no claims bonus charges.
"For 90% of our new business customers we are already fully compliant with this order," a spokesperson said.
"We are part way through a major transformation programme, which when complete will allow us to be fully compliant and enable us to provide best in class service to our members."
Cardiff Airport is to get a £3m loan to develop flight routes as part of £46m Welsh government spending on projects to support the economy.

ScottishPower customers will soon be able to buy gas and electricity in bundles of days rather than signing up to standard or fixed-price deals.

The Co-op has been ordered to provide clearer insurance quotations, after it failed to tell motorists about separate charges for no claims bonuses.
