Dearie me - no IFE must be such a pain! What ever did we do before the Nintendo generation got old enough to fly as long-haul passengers? Let's think:
1. Seats with rather more pitch - particularly for those in 'I paid for my own ticket' class.
2. Civilised multi-course dinners with each course served individually.
3. Appropriate beverages to accompany the above.
4. To travel was almost more enjoyable than to arrive!
Personally I'd far, far sooner have more leg room and a nice leisurely 4- or 5-course meal than an airline tray and a seat-back video which I could just as easily hire at home!!
