"There is a lot of unhappy frontline workers from the pilots upset at his tactics of wage freezes."
The pilot, who spoke anonymously due to contractual commitments with the airline, said the pilots' 3 per cent wage increase limit had translated into a wage reduction because of the speed of modern airlines.
"The Dreamliner (787) is 4 per cent quicker than the Airbus it replaced, it's a very fast aircraft," the captain said.
"We got a 3 per cent pay rise on an aircraft that flies 4 per cent quicker and we get paid by the flight hour, so it was actually a pay cut."
Jetstar refused to drawn on this particular claim.
But a spokesperson from the airline told news.com.au that although the EBA's nominal expiry was in April, it remained in place while the relevant parties nutted out a resolution.
"Since January, we've been in regular and constructive conversations with bargaining representatives about a new enterprise agreement," the spokesperson said.
"There are a number of complex areas to discuss and working through them takes time, but we are committed to do so and optimistic that we will reach an agreement."
The Jetstar pilot said one of the areas of dispute in the discussions was the quality of the food fed to staff while flying, which he provided images of.
"That's the standard crew meal for a captain on a 10-hour Jetstar flight — it's pretty disgusting," he said.
"When I'm trapped at work, it's not like I do a regular job and I can duck off, have 15 minutes out and get a coffee and grab a bite.
"I'm on an aircraft for up to 16 hours. It would be nice to have a meal fit to eat. It's not much."
The pilot said the meals were insufficient, but Jetstar told news.com.au it provided a range of other snacks to supplement up to two meals a flight.
Those snacks included sandwiches, fresh fruit, nuts and yoghurt.
"Meals for our pilots are designed in consultation with qualified dietitians and pilots, and are changed based on pilot feedback," the spokesperson said.
"They include a variety of options and snacks to support the nutritional needs and taste preferences of our crew."
The relevant union for the industry, the Australian Federation of Air Pilots, said EBA negotiations were under way but the issue with the food "continues to disappoint the Jetstar pilots".
