For example, Southwest Airlines boards their planes using a letter-based grouping system. Passengers check in no earlier than 24 hours before their flight and receive a number and letter combination (like A23 or B14). Passengers line up in groups of five, loosely in order and board when your group is called. It’s open seating on Southwest so you get pick your seat.
I don’t think the car service is available for every airline, but is pretty common on business and first class travel on the Middle East Airlines like Etihad and Emirates. I think Etihad will even drive you from Abu Dhabi to Dubai… I tried seeing if they would pick us up in Limerick and drive us across Ireland, a 2+ hour drive, but they limit it to 50km from the airport.
For starters, using an unlocked smartphone when traveling internationally will save you money, as you can purchase local SIM cards and use them for local calling, texting, and, of course, for wireless data to connect you to the internet. This is really helpful as you can tether your other phone, tablet or computer via Bluetooth or Wi-Fi, effectively sharing the connection and avoiding roaming charges. An unlocked phone with a local SIM card means uploads of photos and videos can happen as you take them versus waiting to get somewhere that Wi-Fi is offered. Speeds are faster than roaming and if you’re taking part in business conference calls, those sound better, without the delay that comes about when you roam.
Usually, just having a smile seems to get me what I want. I always ask when I check in however, if there is an upgrade available, if they give extra points for anything, and what specials might be available. Just last night (although at a stage theater) I asked if I could upgrade my row. Although they don't do exchanges, they made an exception and upgraded me 8 rows.
Invest in Luggage: After you figure out if you will be a “carry-on only” or “check only” type of business traveler, invest in a lightweight, durable piece of luggage that has a warranty. The same goes for a laptop bag. Whether you choose a shoulder bag or backpack, make sure it has a lot of padding and distributes weight evenly. You do not want your luggage breaking in the middle of an airport.
