No! Well, AppleCare+ plans for iPhone and iPad purchased in the United States and Canada are only valid in the United States and Canada, but other Apple devices (Apple Watch, Mac, iPod, Apple TV, and Apple displays) provide global coverage. Service options do vary between countries, but any AppleCare service is always performed by authorized techs with genuine Apple parts.
MacBook Air components are officially non-user-replaceable, though third-parties do sell upgrade kits for the SSDs. The flash memory and battery are enclosed within the casing, with RAM soldered onto the motherboard. The flash memory, difficult to access, has a 128 MB cache and a mSATA connection (updated to a proprietary PCIe interface) to the motherboard.
In the current product line, the MacBook Air sits below the performance-range of the MacBook Pro and compared to the MacBook Retina. However, its features reflect different priorities. The Air was originally released as a premium ultraportable positioned above the previous MacBook. Since then, the Air has become Apple's entry-level laptop due to the MacBook's discontinuation in 2011, as well as lowered prices on subsequent iterations.
Much like Apple handles support calls over the phone, soon only customers within their warranty period will be able to access online chat support through getsupport.apple.com for free. For others, Apple will charge what it refers to as a “pay per incident” fee or require the purchase of an extended warranty through AppleCare. Previously all online support chat features were available for free to users worldwide. Some users might have noticed back in August when Apple revamped its support sites that it started listing a $19.99 per incident fee for chat support. However, up until now AppleCare hasn’t actually been charging users to access the feature.
