All airlines have official policies as to when they'll upgrade loyalty program members. Unless an airline has a complimentary space available upgrade program in place, expect that you'll only receive a free upgrade if it's for operational reasons (like if economy is oversold).
So while you shouldn't expect a free upgrade on a flight, you can still ask for upgrades from booking till boarding — and you may be able to pay your way to a much more comfortable seat.
Flight upgrades are difficult to get and are even more impossible to attain if you don't ask for them in the first place. Simply and politely ask for one and remember to smile and be positive--flight attendants and employees won't take too kindly to any sense of entitlement you may give off.
Business and first-class upgrades are popular but they are limited. A good way to increase your chances of getting one is to arrive at check-in several hours early. You might well find you have a lot of time to kill but then you might end up with significantly better seats.
Why You Might Get a "Surprise" Upgrade. In rare circumstances, a flight may be oversold in the economy cabin, but there could be some space in first or business class. In that case, some very lucky passengers might be bumped up to first or business class for free in what's known as an operational upgrade.
The cheapest way to get a business or first-class ticket is to buy an economy ticket then buy an upgrade. You can either do this immediately after booking or look for last-minute upgrades as your travel date approaches. The price for premium cabin fares decreases as you get closer to departure.
Airlines may sell upgrades at a discount when you check-in, either online or at the airport. The closer to the flight departing, the less likely the airline is to sell a cash fare in the upgraded cabin. Thus, they may be open to the idea of offering it to an existing passenger for a discounted price.
Gate agents will typically have a list of frequent fliers who are first eligible for upgrades. So make sure to familiarize yourself with your airline's membership upgrade policies. But if there's no one on the upgrade list, it could be your lucky day. But the process may be different aboard different airlines.
Checking in early increases your chances of getting an upgrade from admin staff if the flight's overbooked. If they know you intend to travel they can upgrade you in advance, so they won't need to shuffle around the upgrades at the airport. It also means if you don't get an upgrade, it's easier to choose the best seat.
Be willing to (politely) ask
Asking at check-in is one of the most obvious yet effective strategies for getting that free upgrade. Generally, hotels upgrade your booking based on status before arrival, but for one reason or another, it can get overlooked.
However, you may be able to purchase an upgrade when you check in for your flight or at your departure gate. You may also be able to use your frequent flyer miles to secure an upgrade. You do not need to have elite status to purchase an upgrade or use miles for an upgrade.
With an in-place upgrade, Windows tries to bring everything from the old version to the new version, which results in the accumulation of many old and unused files, registry entries of certain uninstalled programs, and all other types of garbage. In addition, some programs may not be compatible with the new version.
If luxury and extra legroom is really important to you, book it in advance. However, if you're perfectly willing to fly economy class, and willing to roll the dice, a last-minute upgrade can be the cheapest option. You may even get lucky and score a free upgrade.
First class creates a sense of exclusivity and high prices are necessary to maintain luxurious standards. "When someone does sit in first class, they feel like they're getting outsized value, whether in the form of an upgrade, award, or discounted first-class ticket," writes Schlappig.
Most upgrades from economy or premium economy to business start around $400 and often venture up to $1000. For flights over 7 hours that include fast track, a VIP lounge and a proper bed- $500 seems like a reasonable offer- if the number is comfortable to you.
It's generally a win-win situation for all. Sometimes, op-ups will happen across several cabins. For example, say Economy Class is overbooked but Business Class is also full. In this case, someone from Business might be bumped to First Class, freeing up space for someone to be upgraded from Economy to Business.
It depends on the airline you're flying with, but it is generally cheaper to upgrade to business class at the airport than it is to book a business class ticket from the outset. To upgrade at the airport, you will need to ask about availability and then pay the difference in fare.
When you're flying first class, you want to be able to soak up every part of the experience, and if you're only on board for 1-3 hours, it may not be enough time! If you're flying long haul, however, then first class may be a perfect investment.
Ask about first-class upgrades at the check-in counter
Airlines make more money from filling their flights' first-class seats, so next time you're feeling a little spendy, you can ask at the ticket or boarding counter if there is any availability at the front of the plane.
