An Italian man has launched a lawsuit against Virgin America after a mid-air clash over a drink order and a lavatory visit led to the passenger being detained by police.

Salvatore Francesco Bevivino was travelling from Philadelphia to San Francisco when he pressed the call button so he could order a soda. However, after the flight attendant arrived, she told Bevivino to use his touch screen to place a drink order through the plane's automated system. The 52-year-old apparently refused to do so and asked again for a drink to be brought to him.

The flight staff obliged, but upon landing in San Francisco Bevivino found himself being carted away by police. The airline said it alerted authorities because the passenger was cursing and refusing to follow instructions from the crew. They also claimed Bevivino left a bathroom stall without flushing the toilet.

The passenger denies using profanities or doing anything wrong (his lawyer referred to the unflushed toilet as a "non-event") and says he feels humiliated by the incident. He's suing Virgin America for $500,000 in damages.

Eating out three meals a day can do some serious damage to your travel budget, especially when you want those three meals to be as good as possible. Sure, you could self-cater to save a few bucks, but if you're a real foodie who wants to taste the best a city has to offer, how can you do it without breaking the bank?

Filling up on street food or tracking down food trucks are two tried and true techniques used by backpackers and budget travelers the world over, but those who want to eat at traditional restaurants cut their costs too. Here are five ideas for eating at sit-down restaurants on a budget.

I've always loved a good art gallery but I know not everyone feels the same way. I get it. Looking at still life oil-on-canvases isn't for everyone. But the good news is that some of the coolest art in the world isn't locked away in stuffy art galleries or museums – there are plenty of creative paintings and murals on the sides of buildings, along fences and across public walls.

Graffiti has been around since ancient times but what has really changed is way the many people now perceive the public scribblings. From a mark of gang culture and vandalism to a political statement to genuine artistic expression, graffiti has evolved with the times and is now accepted as "street art" in cities all over the world. Here are a handful of places known for their vibrant street art culture across Europe, South America and The Pacific.

In the hospitality industry, it's becoming increasingly common for hotels to remain open while they're undergoing renovations, or to open their doors to guests while they're still under construction. Known as a "soft opening," it's a way for hotels to recoup costs and train staff while they finish up the building. Usually, a soft opening means the hotel bar is still being completed or the pool is out of order, but occasionally you come across a hotel that has taken the concept to a whole new level.

Reddit user zxphoenix was shocked at what he found when he turned up at the Red Roof Inn in Brentwood, Tenn., this week. The first sign of trouble was the construction scaffolding, which enveloped the building on all sides. Despite the dubious appearance, a "now open" sign can be seen hanging from the metal framework. Handwritten cardboard posters direct guests from the boarded-up lobby to the "front desk," which is little more than a table wedged in a doorway. The hotel guest said of the three floors in the hotel, only one side of the first floor could be considered "livable." That's something of a relative term given that his room door wouldn't fully close, bits of construction debris blew out of the air conditioning unit, and the plumbing sounded like "a pig is being butchered in the pipes."

It's a bad day to be flying with massive closures and flight delays across the country due to a series of technical problems and security breaches.

First up, American Airlines announced that all of its flights would be grounded until at least 5 p.m. CT. An FAA spokesperson said the system-wide outage is the result of computer problems. The airline, which has been besieged by complaints via twitter, says it's working to resolve the issue as quickly as possible.

Meanwhile in New York, part of LaGuardia Airport has been evacuated after a suspicious package was found in the central terminal building. According to Bloomberg, emergency services and the city's bomb squad are on the scene but there are no further details regarding the incident at this point.

And finally in Boston – where security has been tight ever since yesterday's bombing at the Boston Marathon – an aircraft is under investigation. US Airways Flight 1716 has been stopped at Boston Logan Airport because of security concerns, although the exact nature of the threat is unclear.

All of this adds up to gridlock across the nation, with hundreds of flights grounded and passengers delayed, stranded, stuck on planes or unable to make flight reservations. The series of airline troubles come at a bad time for a country already on edge following yesterday's tragedy on the east coast.

Update: 4:04 ET: NBC News reports that a suspicious package at Dallas Fort Worth has been investigated and determined to be a small tire.

Long-distance train travel is making a comeback with Eurostar announcing plans to expand its services. The high-speed train, which primarily serves London, Brussels and Paris, has its sights set on new destinations across the European continent.

Eurostar says its entire system is undergoing an overhaul – from the booking process, to the routes, to the trains themselves. The company's website has been given a facelift in order to create a more user-friendly booking portal, and brand new uniforms have been designed for the crew. Updated trains are also in the pipeline and are expected to be up and running by 2015.

Traveling on a beer budget isn't easy when you have champagne tastes but it seems some vacationers have found a way to cheat their budgets – as well as everyone around them. A survey of British vacationers has revealed the lengths some travelers will go to in order to pinch their pennies, including lying and stealing, among other tactics.

One notorious strategy involves couples pretending to be on their honeymoon in order to score flight or room upgrades, with about 5 percent of survey respondents admitting to faking a special event so they could receive a perk.

Twelve percent of travelers confessed they'd used the pool or other facilities at a hotel they weren't actually a guest of, while 8 percent said they had used another hotel's shuttle bus.

Few people can fly half way around the world just to see an art exhibition, and now, thanks to a new documentary series they don't have to. One company is set to bring culture to the masses by broadcasting major art exhibitions at movie theaters around the globe.

Much like a real trip to a museum, the documentaries walk you through a current or recent exhibit, pausing at important works along the way. A noted historian provides commentary and insight into the significance of the artworks, while interviews with museum curators and a backstage look at the exhibits round out the 90-minute films.

If you're one of those people who start turning green every time your airplane hits a bit of turbulence, you're in for a rough ride in the coming years. According to a new study, air turbulence is likely to go up by 10-40 percent by 2050, causing more passengers to reach for the airsickness bag.

The report published in the Nature Climate Change journal says that clear air turbulence – a sharp movement of air that happens even in good weather – is likely to get worse in the coming decades because of climate change.

The report's authors studied the air over the North Atlantic, which is one of the busiest flight corridors in the world. They believe that as greenhouse gases increase, clear air turbulence will also rise – putting more planes in danger's way. What's more, this particular type of turbulence doesn't show up on an airplane's radar, making it tough for pilots to dodge. Planes that are given a heads up by other aircraft might be able to detour around the turbulence, but that would mean longer flight times and using up more fuel, which in turn contributes to the climate change problem.

But don't start popping the motion sickness pills just yet. Some scientists say the study isn't conclusive and believe there needs to be more research into the matter.

For budget travelers, there's never been a better time to visit the Greek capital. Despite being on the Euro, the country's debt crisis has made this popular tourist center dramatically more affordable than the balance of the European Union, making once expensive resorts now surprisingly reasonable.

As unemployment and other economic problems take their toll, Greeks have all but stopped taking vacations, which means most of the city's tourism bookings rely on foreigners. Unfortunately, many visitors have been scared off by the tide of uncertainty. Fears of a Greek exit from the euro zone and strikes and demonstrations in Athens caused many potential visitors to cancel their bookings – in the first half of last year, the number of tourists visiting fell 9%.

The silver lining to this distress is that for the budget-conscious, it presents a great opportunity. Tourism is the backbone of the Greek economy making up more than 16% of GDP, so the travel industry is bending over backwards to welcome travelers. Hotels, which lost 10-12% in profits last year, have had to drop their prices dramatically to attract tourists. Visiting Athens now means fewer crowds and better deals than ever before.

Athens is also the jumping off point for travel to the Greek Islands. Like the country's capital, the islands have also seen a reduction in the number of tourists and have had to lower their prices accordingly. As an added bonus, the strikes, demonstrations and closures that occasionally afflict the capital are not really felt in the islands.
