Below is a list of popular U.S. airlines and and how long you can go without activity on your account before losing your miles. Activity is defined as any miles in or out for any reason; miles earned or miles redeemed.

If you are getting close to your expiration dates, make sure to visit FreeFrequentFlyerMiles.com for earning opportunities or as a last resort, you can always buy miles directly from the airline. I try to make sure I have activity at least 2 months before my expiration dates to allow ample time for posting.

Most large airlines are members of an alliance which means you can earn and redeem miles for one airline on any of the other carriers in its group. Star Alliance, Skyteam and oneworld are the main alliance groups. My advice is to pick one in each and only earn on those three airlines. Every time you fly check which group you will be flying with and request to earn miles on your chosen airline. When you accrue enough miles for free travel, you can redeem with your choice or any of its partners.

For example, I choose American as my airline in the oneworld alliance. When I fly Lan, another oneworld member, I tell them I’d like to earn American miles. When I have enough miles for a free ticket, I can redeem them on American, Lan or any of the other oneworld carriers.

Here are the airlines included in each alliance:

Star Alliance:

Adria, Air Canada, Air China, Air New Zealand, ANA, Asiana Airlines, Austrian, Blue1, BMI, Brussels Airlines, Continental Airlines, Croatia Airlines, Egyptair, LOT Polish Airlines, Lufthansa, Scandinavian Airlines, Shanghai Airlines, Singapore Airlines, South African Airways, Spanair, Swiss, TAM,TAP Portugal, Thai, Turkish Airlines, United, US Airways

*United and Continental are hoping to merge but it’s unclear if or when this would take effect.

Skyteam:

Aeroflot, AeroMexico, Alitalia, Air France, KLM, China Southern, Delta, Korean Air, Czech Airlines, Air Europa, Kenya Airways

oneworld:

American Airlines, British Airways, Lan, Qantas, Royal Jordanian, Finnair, Iberia, Malev, Mexicana, Japan Airlines, Cathay Pacific

Before a recent trip to Las Vegas, Will received an e-mail with a great offer to stay at the Aria hotel in the brand new City Center complex. Although we all know that staying at a new hotel can be dicey, we figured a luxury property would have to be running relatively smoothly.

Date: December 2009

Parking: Since construction continues on City Center, parking was a mess. There was no back entrance to the self parking lot and we missed the entrance twice forcing us to circle back around the strip. Eventually we used the valet which we stumbled upon by accident. We figured this would make life easier, but the pickup is in a different location so getting our car back was as much a hassle as dropping it off had been.

Check-in/Check-out: We had no wait at the front desk and the woman who helped us was very nice. Although she didn’t have a record of the promotion we had booked, she called a manager over who was able to correct our account. Although it took longer than average, we were satisfied and were given a room on a high floor as requested. Check-out went smoothly and our bill was accurate.

Room: We stayed in a standard room and since we were the first or second guest to stay there it was very clean. Our view was not of the strip, but it was still nice from the floor to ceiling windows. Everything in the room was controlled via a small computer screen on the night table which was somewhat tricky to figure out. I knocked it over during the night causing the curtains to fly open and all the lights to turn on. Overall the room was decent and the bed was comfortable but it seemed unfinished. Wires dangled from the TV, our heat didn’t work, a handle fell off a bathroom drawer and one of the lights above the bed was dangerously loose. I was not impressed at all with the bathroom. The connected shower and bath were strange, the water pressure was horrible, and the sinks had little counter space and splashed water everywhere when used.

Overall Impression: It seemed like a lot of things were thrown together to get the Aria open ASAP even though it’s not really ready. Although all of the employees were very nice, many of them didn’t yet know how things work at the hotel. Hopefully, it will improve with time but I don’t think there should be such a steep learning curve at a 5 star accommodation.

Grade: D+

Date: November 2009

Route: Newark-Lisbon Round-trip

Check-in: Although we were able to select our seats in advance by phone, there was no online check-in so we had to get to the airport early and do it in person. Since we were flying business class, we had a dedicated line and there was no wait but the coach lines weren’t crowded either. In Lisbon, we had access to a special security line and the TAP lounge which had a nice food spread but was crowded and noisy. TAP has no lounge in Newark, but we were given passes to the Virgin Atlantic lounge which was quiet but sparse with no food offered other than bags of pretzels and chips.

Plane: Boarding was fast and easy, even in Lisbon where we had to board by bus. Executive class was given a separate bus and entrance onto the plane which was very efficient as it allowed economy to board simultaneously on another staircase. The business class seats were comfortable to sit in but hard to sleep in. They are cradle-style seats that don’t lean back but slide forward and are angled flat so your head is up and your feet down. It was like sleeping on a hard seesaw with no back support. The cabin temperature was all over the map, sweltering one minute and freezing the next. Although I love being up front, I’ve definitely slept better in a coach seat. We had two bathrooms set aside for business class which meant we rarely had to wait for a turn.

Service: The attendants on both flights were cheerful and attentive. We were given great vanity kits that could hang from the seat back in front of you and were filled with lots of useful things to use during the flight like eye shades, socks and lotion. We were given plenty of drinks, bottled water and a meal service consisting of an appetizer, salad, entree, and dessert. The food was bland and only slightly better than you would expect in coach.

Verdict: Although the TAP employees try hard, top executive class feels more like premium economy than first.

So, is it worth it? JetBlue flights are mostly domestic and generally inexpensive so if you are only taking one or two short flights it may not be. If you are going to fly 2 flights or more and at least one is a long haul, this might be a great deal for you. If you have the time and a bit of money, this would be a great chance to hop around the country visiting friends and family or just exploring for a month.
