Modern air travel has become increasingly unpleasant as airlines continue to shrink seat sizes to fit more passengers on board ' and this is especially true in economy class.But not all airlines are heading in this direction. In fact, many of them are working to increase passenger comfort through new innovations.From coach seats that convert to flat beds to cabin filtration systems that produce cleaner air, here are 10 ways airlines are working to make your coach flight more enjoyable.Coach seats are converting into flat bedsEconomy class usually consists of uncomfortable cramped seats that follow a standard row format. But that's changing. Several airlines have introduced economy seats that can be converted to flat beds, and some have taken that even further.Air New Zealand's Skycouch allows for a row of three economy seats to be converted into a flat bed, all with the push of a button.The arms on the seats retract, while the seat base extends and seat belts lengthen to give you space for reclining.Up to two people can recline together by lying horizontally against the wall. It's been dubbed the "Cuddle Class," and comes at the standard price for each seat, and the third shared seat for half price.Several airlines have copied Air New Zealand's design. China Airlinesoffers an economy class Family Couch, with three economy seats that adjust into a flat bed to accommodate family and friends.The seats come with a mattress protector, pillows, blankets, and a toy for young travelers. The in-flight entertainment system for these seats also features a "Seat Chat" so you can share movies, music, and messaging with one another.There is also Air Astana'sEconomy Sleeper, whichallows passengers the chance to have an entire row of three seats on long-haul flights.The Economy Sleeper has arm rests that fold up and include a mattress, pillow, duvet, complimentary amenity kit, and priority check-in.

Virgin Atlantichas refitted its Boeing 747 aircrafts flying out of London, Gatwick, Manchester, and Glasgow, to include premium economy seats that offer up to 38 inches of seat pitch and 21 inches of width.It's worth noting that the premium economy seats on these airlines cost at least a few hundred dollar more than regular economy, but they're not as expensive as business or first class, and with most airlines, the service also includes priority check-in, boarding, and baggage handling.Even budget US carrier Southwest Airlines added 0.7 inches of extra room to its economy class seating recently.Travelers are using social networks to choose their seatmatesKLM offers travelers the option to select seatmates based on shared interests or connections through Facebook and LinkedIn through itsMeet & Seat program.The program launched in 2012 and passengers who are interested connect their social profiles to their booking before being presented with seat maps that show where others who have also shared their information are sitting.In-flight entertainment is getting betterVirgin America's in-flight entertainment system has seat-to-seat chatting where you can message others on the plane.
