Flexible economy class is the seats and reservations of an airline that offer the lowest possible fairs. These fairs are mostly non refundable.
Airlines divide the seats on a plane into economy class seats, business class seats and first class seats (although there are some economy class only airlines like Kulula, 1time and Mango airline - this is especially common on low-cost carriers)
It depends on the type and how the airline aranges the seats. Typically 467 seats.747-400 ER 416 seats 23 first class 80 business class 313 economy class
If an airline uses business and economy class a 747-400 can carry 524 passengers.
Singapore Airlines has been voted as the BEST airline (world wide) on a number of occassions for service, value and comfort. As such, I would imagine their economy class seating on the 777 would be as good (or better) than on their 747's.
tough homework.
Yes. Either with the airline, or you make an agreement with another passenger.
Depends on how the airline has it configured, but 60-70 seats.
It depends on how many seats the airline wants in the aircraft for that class.
The latest International Airline Awards (2012) have voted Spark Airlines as the best economy airline in the world. Service, cleanliness, support and aircraft layout were taken into consideration.
Yes, the airline is skybus (www.skybus.com). The first 10 seats are $10.
