American Airlines pilot says 1,600 of his furloughed colleagues won't be allowed to fly until August when they complete training - and warns more flights WILL be canceled as shortages creep up across the industry

• Dennis Tajer is an American Airlines Boeing 737 pilot with 30 years experience
• He is also the spokesman for the Allied Pilots Association which represents Americans' 15,000 pilots 
• Over the weekend, irate passengers saw 300 flights canceled across the US
• It was down to a pilot shortage that began with COVID and is now revealing itself as travel rebounds 
• American furloughed 1,600 pilots in October - it was the only major US airline to lay anyone off due to COVID 
• 1,000 pilots took early retirement instead of facing lay-offs
• It's unclear how many American has hired to make up for those losses but even if they rush to, it'll take months to train pilots up 
• American says staff who were furloughed will be back at the end of June  
• Another 1,000 are due to retire from American next year, Tajer said 
• On top of that is a bottleneck building at the rookie level 
• Trainee pilots have not been able to build up flying hours over the last year

An American Airlines pilot says 1,600 of his colleagues who were furloughed in October last year won't be flying again until August because they have to redo their training after so long out of the skies, worsening the staff shortage that caused the airline to cancel more than 300 flights this weekend.

Captain Dennis Tajer has been a pilot with American for more than 20 years. He is also the spokesman for the Allied Pilots Association - the union which represents American's 15,000 pilots. 

On Monday, Capt. Tajer told DailyMail.com that the shortages over the weekend could have been avoided if American had worked with pilots to rearrange their schedules without forcing them to overdo their hours. 

He said that it is the airline's fault they haven't been able to replace the 1,600 pilots that were furloughed last year, or the 1,000 that took early retirement.  

Now, those pilots who were not flying for months must undergo extensive training before they can go back up in the air. It is part of an industry law that after three months out of the sky, pilots must train again. 

But there is huge backlog to training, and not all of those pilots will return. Some have gone on to work as delivery drivers for FedEx or UPS, Tajer said.

What's more, at least 1,000 more pilots are expected to retire next year and with no new recruits able to gain their flying hours before taking jobs, the problem is likely to get worse.   

'It's surreal. This time last year we were canceling flights because there weren't enough passengers. Now we're canceling flights because there aren't enough pilots,' Tajer told DailyMail.com. 

On Sunday, 10,000 flights were delayed across the country due to bad weather including 30% of Southwest's flights, 25% of American's, and 23% of United Airlines and Delta flights. 

At the same time, the weekend saw the highest number of travelers - 2.1 million - since March 2020. 

American has already cut 1,000 flights in the first half of July. 

Tajer doesn't believe that the shortages are down entirely to the COVID-19 furloughs, but says the airline is unwilling to work with the pilots to plug the holes. 

'Instead of coming to us and working with us, they've just surrendered to reducing the schedule.  

 This time last year we were canceling flights because there weren't enough passengers. Now we're canceling flights because there aren't enough pilots' Captain Dennis Tajer, American Airlines

'There's a scheduling problem in that pilots can't accept overtime work legally without maxing out their flying hours.  

'A lot of people who want to help aren't provided the flexibility to help so it narrows the players to a very small margin.  

'But this is the same issue as American was having in 2019- this is not specifically a COVID problem.   We firmly believe we could have sustained the schedule but they didn't consult it. I don't know if their plates were just too full or what,' he said. 

'The first thing AA did was furlough 1,600 pilots in October. No one else did that. 

'Those pilots are still awaiting training and they won't be ready to fly by the end of August. Legally, if you have had a break of three months you have to be trained up again. So the school house is at full tint. 

'Then you have the 1,000 who took early retirement. They've got to fill those positions which takes months and months.  

'We saw this a mile away and we said, "you might have a problem here." They said. "No, we got it."  

'American Airlines took an outlier in that they furloughed staff when no one else did.  Now, here we are,' he said. 

American Airlines told DailyMail.com that the recalled pilots who were furloughed will have completed their training by June. 

A spokesman didn't specify when they would be back in the air, but said: 'The first few weeks of June have brought unprecedented weather to our largest hubs, heavily impacting our operation and causing delays, canceled flights and disruptions to crew member schedules and our customers' plans.  

'That, combined with the labor shortages some of our vendors are contending with and the incredibly quick ramp up of customer demand, has led us to build in additional resilience and certainty to our operation by adjusting a fraction of our scheduled flying through mid-July.' 

She couldn't guarantee more flights would not be canceled, saying: 'At this time, we’re focused on June and the first half of July, but we’ll continue to review and make any needed changes.' 

Tajer says that shortages will be noticed across the board.  

'This will be an industry issue over the next couple of years. It'll be more systemic and based on the institution of pilot flow.'  

Tajer said of the weather explanation: 'Welcome to the big leagues. You don't plan a major airline around one weekend of bad weather.'
